45058729 divided by 879 
Our goal is to divide 45058729 by 879.

Moving on to step 1:
If we divide 4 by 879, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 879

Step 2:
879 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 879

Going ahead to step 3:
If we divide 450 by 879, we get 0 and a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 450, we end up with 450.
Append the next digit (5) from the dividend to 450 and continue with: 4505 / 879

On to step 4:
If we divide 4505 by 879, we get 5 and a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4395 from 4505 to get 110.
Include the next digit (8) from the dividend after 110, then repeat: 1108 / 879

On to step 5:
The number 879 fits into 1108 1 times, leaving a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 229 after subtracting 879 from 1108.
Grab the next digit (7) from the dividend, add it to 229, then carry on: 2297 / 879

Going ahead to step 6:
The number 879 fits into 2297 2 times, leaving a remainder of 539.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
The remainder is 539 after subtracting 1758 from 2297.
Append the next digit (2) from the dividend to 539 and continue with: 5392 / 879

Going ahead to step 7:
879 can be fit into 5392 6 times, resulting in a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 5126.0
The remainder is 118 after subtracting 5274 from 5392.
Include the next digit (9) from the dividend after 118, then repeat: 1189 / 879

Advancing to step 8:
879 can be fit into 1189 1 times, resulting in a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 51261.0
Subtract 879 from 1189 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
The number 879 fits into 3100 3 times, leaving a remainder of 463.
Put 3 as the next digit of the answer. 
Result so far: 51261.3
The remainder is 463 after subtracting 2637 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Going ahead to step 10:
When dividing 4630 by 879, we get 5 with a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 51261.35
The remainder is 235 after subtracting 4395 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 11:
2350 divided by 879 is 2 with a remainder of 592.
The next digit of our result is 2. 
Result so far: 51261.352
If we take 1758 away from 2350, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Moving on to step 12:
The number 879 fits into 5920 6 times, leaving a remainder of 646.
Put 6 as the next digit of the answer. 
Result so far: 51261.3526
If we subtract 5274 from 5920, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 13:
6460 divided by 879 is 7 with a remainder of 307.
The next digit of our result is 7. 
Result so far: 51261.35267
Subtracting 6153 from 6460 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Moving on to step 14:
The number 879 fits into 3070 3 times, leaving a remainder of 433.
Record the quotient 3 as the next digit in the result. 
Result so far: 51261.352673
Subtract 2637 from 3070 to get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Let's proceed to step 15:
4330 divided by 879 is 4 with a remainder of 814.
Put 4 as the next digit of the answer. 
Result so far: 51261.3526734
Deduct 3516 from 4330 and we're left with 814.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8140, and continue the process.

On to step 16:
When dividing 8140 by 879, we get 9 with a remainder of 229.
Use 9 as the next digit of our solution. 
Result so far: 51261.35267349
Deduct 7911 from 8140 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The final outcome is 51261.35267349, with a leftover of 2.29e-07.
