We're dividing 77137918 by 687 
The aim is to understand the frequency of 687 in 77137918.

Step 1:
If we divide 7 by 687, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 687

Going ahead to step 2:
The number 687 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 687

Advancing to step 3:
687 can be fit into 771 1 times, resulting in a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 687 away from 771, we end up with 84.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 687

Going ahead to step 4:
When dividing 843 by 687, we get 1 with a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 687 from 843, we get 156.
Fetch the next digit (7) from the dividend, attach it to 156 and continue: 1567 / 687

Step 5:
1567 divided by 687 is 2 with a remainder of 193.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtract 1374 from 1567 to get 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 687

Let's proceed to step 6:
687 goes into 1939 2 times with a remainder of 565.
Use 2 as the next digit of our solution. 
Result so far: 1122.0
If we take 1374 away from 1939, we end up with 565.
Bring next digit (1) of the dividend behind the 565 and repeat the process: 5651 / 687

Advancing to step 7:
When dividing 5651 by 687, we get 8 with a remainder of 155.
Put 8 as the next digit of the answer. 
Result so far: 11228.0
The remainder is 155 after subtracting 5496 from 5651.
Append the next digit (8) from the dividend to 155 and continue with: 1558 / 687

On to step 8:
The number 687 fits into 1558 2 times, leaving a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 112282.0
The remainder is 184 after subtracting 1374 from 1558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
If we divide 1840 by 687, we get 2 and a remainder of 466.
Put 2 as the next digit of the answer. 
Result so far: 112282.2
The remainder is 466 after subtracting 1374 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 10:
4660 divided by 687 is 6 with a remainder of 538.
Use 6 as the next digit of our solution. 
Result so far: 112282.26
If we subtract 4122 from 4660, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Going ahead to step 11:
If we divide 5380 by 687, we get 7 and a remainder of 571.
The next digit of our result is 7. 
Result so far: 112282.267
If we subtract 4809 from 5380, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Moving on to step 12:
When dividing 5710 by 687, we get 8 with a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 112282.2678
Subtracting 5496 from 5710 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 13:
687 goes into 2140 3 times with a remainder of 79.
The next digit of our result is 3. 
Result so far: 112282.26783
If we take 2061 away from 2140, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 14:
The number 687 fits into 790 1 times, leaving a remainder of 103.
Record the quotient 1 as the next digit in the result. 
Result so far: 112282.267831
Subtract 687 from 790 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 15:
When dividing 1030 by 687, we get 1 with a remainder of 343.
The number 1 becomes the next digit in our result. 
Result so far: 112282.2678311
Subtracting 687 from 1030 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

In conclusion, the division gives 112282.2678311 with a balance of 3.43e-06.
