We look at the division of 77712605 by 137 
The aim is to understand the frequency of 137 in 77712605.

On to step 1:
137 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 137

On to step 2:
When dividing 77 by 137, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 137

Moving on to step 3:
If we divide 777 by 137, we get 5 and a remainder of 92.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 685 away from 777, we end up with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 137

Step 4:
If we divide 921 by 137, we get 6 and a remainder of 99.
Write down 6 as next digit of the result. 
Result so far: 56.0
The remainder is 99 after subtracting 822 from 921.
Bring next digit (2) of the dividend behind the 99 and repeat the process: 992 / 137

Moving on to step 5:
When dividing 992 by 137, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 567.0
If we subtract 959 from 992, we get 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 137

Let's proceed to step 6:
137 can be fit into 336 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 5672.0
Deduct 274 from 336 and we're left with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 137

Going ahead to step 7:
137 can be fit into 620 4 times, resulting in a remainder of 72.
The next digit of our result is 4. 
Result so far: 56724.0
If we take 548 away from 620, we end up with 72.
Grab the next digit (5) from the dividend, add it to 72, then carry on: 725 / 137

Going ahead to step 8:
137 can be fit into 725 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 567245.0
The remainder is 40 after subtracting 685 from 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 137, we get 2 with a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 567245.2
The remainder is 126 after subtracting 274 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 10:
137 goes into 1260 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 567245.29
Subtract 1233 from 1260 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
The number 137 fits into 270 1 times, leaving a remainder of 133.
Use 1 as the next digit of our solution. 
Result so far: 567245.291
If we take 137 away from 270, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 12:
If we divide 1330 by 137, we get 9 and a remainder of 97.
The number 9 becomes the next digit in our result. 
Result so far: 567245.2919
Subtracting 1233 from 1330 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 13:
If we divide 970 by 137, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 567245.29197
Subtract 959 from 970 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
137 can be fit into 110 0 times, resulting in a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 567245.29197
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 15:
137 can be fit into 1100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 567245.2919708
Subtract 1096 from 1100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 16:
40 divided by 137 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 567245.2919708
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 567245.2919708 with a balance of 4e-08.
