We look at the division of 83552686 by 707 
The aim is to understand the frequency of 707 in 83552686.

Step 1:
If we divide 8 by 707, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 707

Step 2:
707 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 707

Step 3:
835 divided by 707 is 1 with a remainder of 128.
The next digit of our result is 1. 
Result so far: 1.0
If we take 707 away from 835, we end up with 128.
Include the next digit (5) from the dividend after 128, then repeat: 1285 / 707

Step 4:
When dividing 1285 by 707, we get 1 with a remainder of 578.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 707 from 1285, we get 578.
Fetch the next digit (2) from the dividend, attach it to 578 and continue: 5782 / 707

Moving on to step 5:
5782 divided by 707 is 8 with a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 5656 from 5782 and we're left with 126.
Take the next digit (6) from the dividend and append it to 126, then repeat: 1266 / 707

Advancing to step 6:
707 can be fit into 1266 1 times, resulting in a remainder of 559.
Write down 1 as next digit of the result. 
Result so far: 1181.0
Subtract 707 from 1266 to get 559.
Append the next digit (8) from the dividend to 559 and continue with: 5598 / 707

On to step 7:
707 can be fit into 5598 7 times, resulting in a remainder of 649.
Record the quotient 7 as the next digit in the result. 
Result so far: 11817.0
Subtract 4949 from 5598 to get 649.
Take the next digit (6) from the dividend and append it to 649, then repeat: 6496 / 707

Let's proceed to step 8:
When dividing 6496 by 707, we get 9 with a remainder of 133.
Record the quotient 9 as the next digit in the result. 
Result so far: 118179.0
Deduct 6363 from 6496 and we're left 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.

Advancing to step 9:
707 can be fit into 1330 1 times, resulting in a remainder of 623.
The next digit of our result is 1. 
Result so far: 118179.1
Subtracting 707 from 1330 leaves us with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 10:
If we divide 6230 by 707, we get 8 and a remainder of 574.
Put 8 as the next digit of the answer. 
Result so far: 118179.18
Subtracting 5656 from 6230 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 11:
707 goes into 5740 8 times with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 118179.188
Subtract 5656 from 5740 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 118179.188 with a remainder of 0.0084.
