Let's divide 86685654 by 628
The aim is to understand the frequency of 628 in 86685654.

Step 1:
When dividing 8 by 628, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 628

On to step 2:
628 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 628

Let's proceed to step 3:
628 goes into 866 1 times with a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 628 away from 866, we end up with 238.
Fetch the next digit (8) from the dividend, attach it to 238 and continue: 2388 / 628

Advancing to step 4:
628 can be fit into 2388 3 times, resulting in a remainder of 504.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 1884 from 2388 and we're left with 504.
Append the next digit (5) from the dividend to 504 and continue with: 5045 / 628

Let's proceed to step 5:
If we divide 5045 by 628, we get 8 and a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we take 5024 away from 5045, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 628

Step 6:
216 divided by 628 is 0 with a remainder of 216.
The next digit of our result is 0. 
Result so far: 1380.0
Deduct 0 from 216 and we're left with 216.
Bring next digit (5) of the dividend behind the 216 and repeat the process: 2165 / 628

Advancing to step 7:
628 can be fit into 2165 3 times, resulting in a remainder of 281.
Write down 3 as next digit of the result. 
Result so far: 13803.0
The remainder is 281 after subtracting 1884 from 2165.
Fetch the next digit (4) from the dividend, attach it to 281 and continue: 2814 / 628

Advancing to step 8:
If we divide 2814 by 628, we get 4 and a remainder of 302.
Record the quotient 4 as the next digit in the result. 
Result so far: 138034.0
If we take 2512 away from 2814, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Let's proceed to step 9:
If we divide 3020 by 628, we get 4 and a remainder of 508.
Write down 4 as next digit of the result. 
Result so far: 138034.4
If we subtract 2512 from 3020, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 10:
The number 628 fits into 5080 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 138034.48
The remainder is 56 after subtracting 5024 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
560 divided by 628 is 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 138034.48
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 12:
The number 628 fits into 5600 8 times, leaving a remainder of 576.
The next digit of our result is 8. 
Result so far: 138034.4808
Subtract 5024 from 5600 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 13:
The number 628 fits into 5760 9 times, leaving a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 138034.48089
Subtract 5652 from 5760 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
If we divide 1080 by 628, we get 1 and a remainder of 452.
Write down 1 as next digit of the result. 
Result so far: 138034.480891
If we take 628 away from 1080, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 15:
4520 divided by 628 is 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 138034.4808917
The remainder is 124 after subtracting 4396 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 16:
628 can be fit into 1240 1 times, resulting in a remainder of 612.
Put 1 as the next digit of the answer. 
Result so far: 138034.48089171
Deduct 628 from 1240 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

The quotient of the division is 138034.48089171, and the remainder is 6.12e-07.
