961731 divided by 63 
The aim is to understand the frequency of 63 in 961731.

Going ahead to step 1:
When dividing 9 by 63, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 63

Advancing to step 2:
The number 63 fits into 96 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 63 away from 96, we end up with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 63

Advancing to step 3:
63 can be fit into 331 5 times, resulting in a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 315 from 331, we get 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 63

Advancing to step 4:
63 can be fit into 167 2 times, resulting in a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtracting 126 from 167 leaves us with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 63

On to step 5:
The number 63 fits into 413 6 times, leaving a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 1526.0
If we subtract 378 from 413, we get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 63

Let's proceed to step 6:
63 goes into 351 5 times with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 15265.0
The remainder is 36 after subtracting 315 from 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
360 divided by 63 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 15265.5
Subtract 315 from 360 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
If we divide 450 by 63, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 15265.57
If we take 441 away from 450, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
When dividing 90 by 63, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 15265.571
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
63 can be fit into 270 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 15265.5714
The remainder is 18 after subtracting 252 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
When dividing 180 by 63, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 15265.57142
If we subtract 126 from 180, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
63 can be fit into 540 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 15265.571428
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
63 goes into 360 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 15265.5714285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
63 can be fit into 450 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 15265.57142857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 15265.57142857, with a leftover of 9e-09.
