We look at the division of 40245553 by 879 
We want to figure out the number of times 40245553 can be divided by 879.

Moving on to step 1:
879 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 879

Going ahead to step 2:
If we divide 40 by 879, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 879

Advancing to step 3:
879 can be fit into 402 0 times, resulting in a remainder of 402.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 402 leaves us with 402.
Include the next digit (4) from the dividend after 402, then repeat: 4024 / 879

Advancing to step 4:
4024 divided by 879 is 4 with a remainder of 508.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3516 from 4024 to get 508.
Grab the next digit (5) from the dividend, add it to 508, then carry on: 5085 / 879

Advancing to step 5:
If we divide 5085 by 879, we get 5 and a remainder of 690.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 690 after subtracting 4395 from 5085.
Fetch the next digit (5) from the dividend, attach it to 690 and continue: 6905 / 879

On to step 6:
879 goes into 6905 7 times with a remainder of 752.
Record the quotient 7 as the next digit in the result. 
Result so far: 457.0
If we take 6153 away from 6905, we end up with 752.
Grab the next digit (5) from the dividend, add it to 752, then carry on: 7525 / 879

Advancing to step 7:
If we divide 7525 by 879, we get 8 and a remainder of 493.
Use 8 as the next digit of our solution. 
Result so far: 4578.0
Subtracting 7032 from 7525 leaves us with 493.
Bring next digit (3) of the dividend behind the 493 and repeat the process: 4933 / 879

Going ahead to step 8:
879 can be fit into 4933 5 times, resulting in a remainder of 538.
Put 5 as the next digit of the answer. 
Result so far: 45785.0
Deduct 4395 from 4933 and we're left with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 9:
When dividing 5380 by 879, we get 6 with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 45785.6
The remainder is 106 after subtracting 5274 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 10:
879 goes into 1060 1 times with a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 45785.61
The remainder is 181 after subtracting 879 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 11:
879 goes into 1810 2 times with a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 45785.612
If we take 1758 away from 1810, we end up 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.

Let's proceed to step 12:
When dividing 520 by 879, we get 0 with a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 45785.612
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
If we divide 5200 by 879, we get 5 and a remainder of 805.
Write down 5 as next digit of the result. 
Result so far: 45785.61205
The remainder is 805 after subtracting 4395 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Moving on to step 14:
879 can be fit into 8050 9 times, resulting in a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 45785.612059
The remainder is 139 after subtracting 7911 from 8050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 15:
When dividing 1390 by 879, we get 1 with a remainder of 511.
Put 1 as the next digit of the answer. 
Result so far: 45785.6120591
If we take 879 away from 1390, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 16:
5110 divided by 879 is 5 with a remainder of 715.
Use 5 as the next digit of our solution. 
Result so far: 45785.61205915
The remainder is 715 after subtracting 4395 from 5110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

The final outcome is 45785.61205915, with a leftover of 7.15e-07.
