We look at the division of 53401544 by 627 
The aim is to understand the frequency of 627 in 53401544.

On to step 1:
627 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 627

On to step 2:
If we divide 53 by 627, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 627

Step 3:
627 can be fit into 534 0 times, resulting in a remainder of 534.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 534 after subtracting 0 from 534.
Take the next digit (0) from the dividend and append it to 534, then repeat: 5340 / 627

On to step 4:
627 goes into 5340 8 times with a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5016 from 5340, we get 324.
Take the next digit (1) from the dividend and append it to 324, then repeat: 3241 / 627

On to step 5:
The number 627 fits into 3241 5 times, leaving a remainder of 106.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 106 after subtracting 3135 from 3241.
Grab the next digit (5) from the dividend, add it to 106, then carry on: 1065 / 627

Step 6:
627 can be fit into 1065 1 times, resulting in a remainder of 438.
Use 1 as the next digit of our solution. 
Result so far: 851.0
Deduct 627 from 1065 and we're left with 438.
Include the next digit (4) from the dividend after 438, then repeat: 4384 / 627

On to step 7:
If we divide 4384 by 627, we get 6 and a remainder of 622.
The next digit of our result is 6. 
Result so far: 8516.0
Subtracting 3762 from 4384 leaves us with 622.
Append the next digit (4) from the dividend to 622 and continue with: 6224 / 627

Moving on to step 8:
6224 divided by 627 is 9 with a remainder of 581.
Put 9 as the next digit of the answer. 
Result so far: 85169.0
If we subtract 5643 from 6224, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 9:
5810 divided by 627 is 9 with a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 85169.9
If we take 5643 away from 5810, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 10:
1670 divided by 627 is 2 with a remainder of 416.
Put 2 as the next digit of the answer. 
Result so far: 85169.92
The remainder is 416 after subtracting 1254 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 11:
4160 divided by 627 is 6 with a remainder of 398.
Record the quotient 6 as the next digit in the result. 
Result so far: 85169.926
The remainder is 398 after subtracting 3762 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 12:
The number 627 fits into 3980 6 times, leaving a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 85169.9266
Deduct 3762 from 3980 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The quotient of the division is 85169.9266, and the remainder is 0.00218.
