138724 ÷ 63 
The aim is to understand the frequency of 63 in 138724.

Moving on to step 1:
63 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 63

Going ahead to step 2:
The number 63 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 63

Advancing to step 3:
The number 63 fits into 138 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 126 away from 138, we end up with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 63

Let's proceed to step 4:
If we divide 127 by 63, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 126 from 127 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 63

Moving on to step 5:
The number 63 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 220.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 63

Step 6:
If we divide 124 by 63, we get 1 and a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 2201.0
If we take 63 away from 124, we end up 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.

Advancing to step 7:
63 can be fit into 610 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 2201.9
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.

Advancing to step 8:
When dividing 430 by 63, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 2201.96
The remainder is 52 after subtracting 378 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
When dividing 520 by 63, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 2201.968
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.

Advancing to step 10:
63 can be fit into 160 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 2201.9682
Subtracting 126 from 160 leaves us 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.

Advancing to step 11:
When dividing 340 by 63, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2201.96825
If we subtract 315 from 340, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
The number 63 fits into 250 3 times, leaving a remainder of 61.
The next digit of our result is 3. 
Result so far: 2201.968253
The remainder is 61 after subtracting 189 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
610 divided by 63 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 2201.9682539
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.

Step 14:
When dividing 430 by 63, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 2201.96825396
Subtracting 378 from 430 leaves us 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.

The final outcome is 2201.96825396, with a leftover of 5.2e-08.
