We look at the division of 84275546 by 637 
The aim is to understand the frequency of 637 in 84275546.

Advancing to step 1:
8 divided by 637 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 637

Advancing to step 2:
84 divided by 637 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 637

Moving on to step 3:
842 divided by 637 is 1 with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 637 away from 842, we end up with 205.
Include the next digit (7) from the dividend after 205, then repeat: 2057 / 637

On to step 4:
2057 divided by 637 is 3 with a remainder of 146.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1911 from 2057, we get 146.
Append the next digit (5) from the dividend to 146 and continue with: 1465 / 637

Advancing to step 5:
When dividing 1465 by 637, we get 2 with a remainder of 191.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Deduct 1274 from 1465 and we're left with 191.
Grab the next digit (5) from the dividend, add it to 191, then carry on: 1915 / 637

On to step 6:
637 goes into 1915 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1323.0
If we take 1911 away from 1915, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 637

Going ahead to step 7:
637 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 13230.0
Subtract 0 from 44 to get 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 637

Going ahead to step 8:
The number 637 fits into 446 0 times, leaving a remainder of 446.
The next digit of our result is 0. 
Result so far: 132300.0
Subtracting 0 from 446 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
The number 637 fits into 4460 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 132300.7
If we subtract 4459 from 4460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 637, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 132300.7
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 637, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 132300.7
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 132300.7 with a remaining 0.01.
