We look at the division of 77742918 by 637 
The aim is to understand the frequency of 637 in 77742918.

Step 1:
637 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 637

Moving on to step 2:
If we divide 77 by 637, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 637

Moving on to step 3:
The number 637 fits into 777 1 times, leaving a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 637 from 777 and we're left with 140.
Include the next digit (4) from the dividend after 140, then repeat: 1404 / 637

Advancing to step 4:
When dividing 1404 by 637, we get 2 with a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1274 away from 1404, we end up with 130.
Bring next digit (2) of the dividend behind the 130 and repeat the process: 1302 / 637

Going ahead to step 5:
If we divide 1302 by 637, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtracting 1274 from 1302 leaves us with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 637

Moving on to step 6:
637 can be fit into 289 0 times, resulting in a remainder of 289.
Use 0 as the next digit of our solution. 
Result so far: 1220.0
The remainder is 289 after subtracting 0 from 289.
Append the next digit (1) from the dividend to 289 and continue with: 2891 / 637

Let's proceed to step 7:
637 can be fit into 2891 4 times, resulting in a remainder of 343.
The number 4 becomes the next digit in our result. 
Result so far: 12204.0
If we subtract 2548 from 2891, we get 343.
Include the next digit (8) from the dividend after 343, then repeat: 3438 / 637

On to step 8:
When dividing 3438 by 637, we get 5 with a remainder of 253.
The next digit of our result is 5. 
Result so far: 122045.0
The remainder is 253 after subtracting 3185 from 3438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 9:
637 goes into 2530 3 times with a remainder of 619.
Use 3 as the next digit of our solution. 
Result so far: 122045.3
If we subtract 1911 from 2530, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Moving on to step 10:
The number 637 fits into 6190 9 times, leaving a remainder of 457.
Use 9 as the next digit of our solution. 
Result so far: 122045.39
If we take 5733 away from 6190, we end up with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 11:
When dividing 4570 by 637, we get 7 with a remainder of 111.
The next digit of our result is 7. 
Result so far: 122045.397
Subtract 4459 from 4570 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 12:
637 can be fit into 1110 1 times, resulting in a remainder of 473.
Record the quotient 1 as the next digit in the result. 
Result so far: 122045.3971
If we subtract 637 from 1110, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 13:
The number 637 fits into 4730 7 times, leaving a remainder of 271.
The number 7 becomes the next digit in our result. 
Result so far: 122045.39717
Subtracting 4459 from 4730 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 14:
The number 637 fits into 2710 4 times, leaving a remainder of 162.
Record the quotient 4 as the next digit in the result. 
Result so far: 122045.397174
Subtracting 2548 from 2710 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 15:
If we divide 1620 by 637, we get 2 and a remainder of 346.
Write down 2 as next digit of the result. 
Result so far: 122045.3971742
Subtracting 1274 from 1620 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 16:
The number 637 fits into 3460 5 times, leaving a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 122045.39717425
Subtracting 3185 from 3460 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The final result is 122045.39717425 with a remainder of 2.75e-07.
