We look at the division of 88863573 by 637 
The aim is to understand the frequency of 637 in 88863573.

Moving on to step 1:
637 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 637

On to step 2:
88 divided by 637 is 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Fetch the next digit (8) from the dividend, attach it to 88 and continue: 888 / 637

Step 3:
888 divided by 637 is 1 with a remainder of 251.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 637 from 888 to get 251.
Include the next digit (6) from the dividend after 251, then repeat: 2516 / 637

Advancing to step 4:
If we divide 2516 by 637, we get 3 and a remainder of 605.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 605 after subtracting 1911 from 2516.
Grab the next digit (3) from the dividend, add it to 605, then carry on: 6053 / 637

Moving on to step 5:
If we divide 6053 by 637, we get 9 and a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 5733 from 6053 leaves us with 320.
Bring next digit (5) of the dividend behind the 320 and repeat the process: 3205 / 637

Going ahead to step 6:
3205 divided by 637 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1395.0
Deduct 3185 from 3205 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 637

On to step 7:
637 goes into 207 0 times with a remainder of 207.
The number 0 becomes the next digit in our result. 
Result so far: 13950.0
If we take 0 away from 207, we end up with 207.
Fetch the next digit (3) from the dividend, attach it to 207 and continue: 2073 / 637

Step 8:
637 goes into 2073 3 times with a remainder of 162.
The number 3 becomes the next digit in our result. 
Result so far: 139503.0
The remainder is 162 after subtracting 1911 from 2073.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
If we divide 1620 by 637, we get 2 and a remainder of 346.
Record the quotient 2 as the next digit in the result. 
Result so far: 139503.2
If we take 1274 away from 1620, we end up 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.

Step 10:
If we divide 3460 by 637, we get 5 and a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 139503.25
Subtract 3185 from 3460 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
637 goes into 2750 4 times with a remainder of 202.
Put 4 as the next digit of the answer. 
Result so far: 139503.254
If we subtract 2548 from 2750, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 12:
The number 637 fits into 2020 3 times, leaving a remainder of 109.
Put 3 as the next digit of the answer. 
Result so far: 139503.2543
If we subtract 1911 from 2020, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 13:
637 can be fit into 1090 1 times, resulting in a remainder of 453.
The number 1 becomes the next digit in our result. 
Result so far: 139503.25431
If we subtract 637 from 1090, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Advancing to step 14:
4530 divided by 637 is 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 139503.254317
Subtracting 4459 from 4530 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 15:
When dividing 710 by 637, we get 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 139503.2543171
The remainder is 73 after subtracting 637 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 16:
637 goes into 730 1 times with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 139503.25431711
Deduct 637 from 730 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

After the division, we end up with 139503.25431711 and a remainder of 9.3e-08.
