63163729 ÷ 872 
Our goal is to divide 63163729 by 872.

Going ahead to step 1:
If we divide 6 by 872, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 872

Going ahead to step 2:
872 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 872

Advancing to step 3:
The number 872 fits into 631 0 times, leaving a remainder of 631.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 631 to get 631.
Take the next digit (6) from the dividend and append it to 631, then repeat: 6316 / 872

Going ahead to step 4:
6316 divided by 872 is 7 with a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 6104 from 6316 and we're left with 212.
Take the next digit (3) from the dividend and append it to 212, then repeat: 2123 / 872

Advancing to step 5:
872 goes into 2123 2 times with a remainder of 379.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 1744 from 2123 and we're left with 379.
Append the next digit (7) from the dividend to 379 and continue with: 3797 / 872

Step 6:
If we divide 3797 by 872, we get 4 and a remainder of 309.
Write down 4 as next digit of the result. 
Result so far: 724.0
The remainder is 309 after subtracting 3488 from 3797.
Fetch the next digit (2) from the dividend, attach it to 309 and continue: 3092 / 872

Going ahead to step 7:
3092 divided by 872 is 3 with a remainder of 476.
Write down 3 as next digit of the result. 
Result so far: 7243.0
Deduct 2616 from 3092 and we're left with 476.
Fetch the next digit (9) from the dividend, attach it to 476 and continue: 4769 / 872

Moving on to step 8:
872 can be fit into 4769 5 times, resulting in a remainder of 409.
Write down 5 as next digit of the result. 
Result so far: 72435.0
Subtracting 4360 from 4769 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 9:
872 can be fit into 4090 4 times, resulting in a remainder of 602.
The next digit of our result is 4. 
Result so far: 72435.4
Subtract 3488 from 4090 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 10:
6020 divided by 872 is 6 with a remainder of 788.
Put 6 as the next digit of the answer. 
Result so far: 72435.46
Deduct 5232 from 6020 and we're left with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Going ahead to step 11:
The number 872 fits into 7880 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 72435.469
The remainder is 32 after subtracting 7848 from 7880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
When dividing 320 by 872, we get 0 with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 72435.469
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
872 goes into 3200 3 times with a remainder of 584.
The next digit of our result is 3. 
Result so far: 72435.46903
If we take 2616 away from 3200, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 14:
The number 872 fits into 5840 6 times, leaving a remainder of 608.
Put 6 as the next digit of the answer. 
Result so far: 72435.469036
The remainder is 608 after subtracting 5232 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 15:
872 can be fit into 6080 6 times, resulting in a remainder of 848.
Put 6 as the next digit of the answer. 
Result so far: 72435.4690366
Subtracting 5232 from 6080 leaves us with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

The final outcome is 72435.4690366, with a leftover of 8.48e-06.
