We look at the division of 988174 by 63 
The aim is to understand the frequency of 63 in 988174.

Advancing to step 1:
63 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 63

On to step 2:
63 goes into 98 1 times with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 63 from 98 and we're left with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 63

On to step 3:
The number 63 fits into 358 5 times, leaving a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 315 from 358, we get 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 63

On to step 4:
63 can be fit into 431 6 times, resulting in a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
The remainder is 53 after subtracting 378 from 431.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 63

Going ahead to step 5:
The number 63 fits into 537 8 times, leaving a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 1568.0
The remainder is 33 after subtracting 504 from 537.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 63

Step 6:
63 goes into 334 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 15685.0
The remainder is 19 after subtracting 315 from 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
63 goes into 190 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 15685.3
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
The number 63 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 15685.3
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.

Step 9:
63 can be fit into 100 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 15685.301
Deduct 63 from 100 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
If we divide 370 by 63, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 15685.3015
Subtracting 315 from 370 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 11:
When dividing 550 by 63, we get 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 15685.30158
Subtracting 504 from 550 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
63 can be fit into 460 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 15685.301587
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
When dividing 190 by 63, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 15685.3015873
Subtract 189 from 190 to 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.

On to step 14:
If we divide 10 by 63, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15685.3015873
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 15685.3015873 and a remainder of 1e-08.
