We're dividing 139998 by 63 
The aim is to understand the frequency of 63 in 139998.

Moving on to step 1:
1 divided by 63 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 63

Going ahead to step 2:
If we divide 13 by 63, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 63

Moving on to step 3:
When dividing 139 by 63, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 126 from 139 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 63

Going ahead to step 4:
The number 63 fits into 139 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 126 from 139, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 63

On to step 5:
If we divide 139 by 63, we get 2 and a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 222.0
Deduct 126 from 139 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 63

Step 6:
If we divide 138 by 63, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2222.0
Subtracting 126 from 138 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
If we divide 120 by 63, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 2222.1
The remainder is 57 after subtracting 63 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
63 goes into 570 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2222.19
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
63 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2222.19
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
When dividing 300 by 63, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 2222.1904
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
When dividing 480 by 63, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 2222.19047
The remainder is 39 after subtracting 441 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
When dividing 390 by 63, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 2222.190476
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 63, we get 1 and a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 2222.1904761
If we take 63 away from 120, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 14:
63 can be fit into 570 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2222.19047619
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 2222.19047619 with a remainder of 3e-09.
