We're dividing 7798126 by 63 
Our goal is to divide 7798126 by 63.

Step 1:
63 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 63

Advancing to step 2:
63 goes into 77 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 63 from 77 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 63

Advancing to step 3:
149 divided by 63 is 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 126 from 149 to get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 63

Let's proceed to step 4:
The number 63 fits into 238 3 times, leaving a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtracting 189 from 238 leaves us with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 63

On to step 5:
If we divide 491 by 63, we get 7 and a remainder of 50.
The next digit of our result is 7. 
Result so far: 1237.0
Subtracting 441 from 491 leaves us with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 63

Going ahead to step 6:
When dividing 502 by 63, we get 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 12377.0
If we subtract 441 from 502, we get 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 63

Moving on to step 7:
If we divide 616 by 63, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 123779.0
Deduct 567 from 616 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
63 can be fit into 490 7 times, resulting in a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 123779.7
Subtracting 441 from 490 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
63 goes into 490 7 times with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 123779.77
The remainder is 49 after subtracting 441 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 123779.77, with a leftover of 0.049.
