We look at the division of 253100 by 63 
The aim is to understand the frequency of 63 in 253100.

Going ahead to step 1:
The number 63 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 63

On to step 2:
63 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 63

Advancing to step 3:
If we divide 253 by 63, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 252 from 253.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 63

On to step 4:
63 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 11, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 63

Going ahead to step 5:
When dividing 110 by 63, we get 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 401.0
Subtracting 63 from 110 leaves us with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 63

On to step 6:
63 goes into 470 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 4017.0
Subtracting 441 from 470 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 63, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 4017.4
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
The number 63 fits into 380 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 4017.46
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
20 divided by 63 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4017.46
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
63 goes into 200 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 4017.4603
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 63, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 4017.46031
The remainder is 47 after subtracting 63 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
The number 63 fits into 470 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 4017.460317
Subtract 441 from 470 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
If we divide 290 by 63, we get 4 and a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 4017.4603174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
63 goes into 380 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 4017.46031746
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 4017.46031746 and a remainder of 2e-09.
