We divide 386647 by 63
The aim is to understand the frequency of 63 in 386647.

Going ahead to step 1:
The number 63 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 63

Advancing to step 2:
63 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 63

Step 3:
386 divided by 63 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 378 from 386 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 63

Going ahead to step 4:
If we divide 86 by 63, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 61.0
If we subtract 63 from 86, we get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 63

On to step 5:
The number 63 fits into 234 3 times, leaving a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 613.0
Deduct 189 from 234 and we're left with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 63

Step 6:
63 can be fit into 457 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 6137.0
Deduct 441 from 457 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 63, we get 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 6137.2
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
When dividing 340 by 63, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6137.25
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
250 divided by 63 is 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 6137.253
Deduct 189 from 250 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 10:
If we divide 610 by 63, we get 9 and a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 6137.2539
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 11:
The number 63 fits into 430 6 times, leaving a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6137.25396
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
63 goes into 520 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 6137.253968
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 63, we get 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 6137.2539682
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
63 goes into 340 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6137.25396825
Subtracting 315 from 340 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 6137.25396825, with a leftover of 2.5e-08.
