39072579 ÷ 856 
We're looking to find how many times 856 goes into 39072579.

Moving on to step 1:
856 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 856

Step 2:
If we divide 39 by 856, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 856

On to step 3:
If we divide 390 by 856, we get 0 and a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 390, we get 390.
Fetch the next digit (7) from the dividend, attach it to 390 and continue: 3907 / 856

On to step 4:
856 goes into 3907 4 times with a remainder of 483.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 483 after subtracting 3424 from 3907.
Grab the next digit (2) from the dividend, add it to 483, then carry on: 4832 / 856

On to step 5:
856 can be fit into 4832 5 times, resulting in a remainder of 552.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 4280 from 4832 and we're left with 552.
Take the next digit (5) from the dividend and append it to 552, then repeat: 5525 / 856

On to step 6:
If we divide 5525 by 856, we get 6 and a remainder of 389.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Subtracting 5136 from 5525 leaves us with 389.
Grab the next digit (7) from the dividend, add it to 389, then carry on: 3897 / 856

Let's proceed to step 7:
856 can be fit into 3897 4 times, resulting in a remainder of 473.
Use 4 as the next digit of our solution. 
Result so far: 4564.0
Subtracting 3424 from 3897 leaves us with 473.
Bring next digit (9) of the dividend behind the 473 and repeat the process: 4739 / 856

Moving on to step 8:
856 can be fit into 4739 5 times, resulting in a remainder of 459.
The next digit of our result is 5. 
Result so far: 45645.0
Subtracting 4280 from 4739 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 9:
If we divide 4590 by 856, we get 5 and a remainder of 310.
The next digit of our result is 5. 
Result so far: 45645.5
Subtract 4280 from 4590 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.

Advancing to step 10:
When dividing 3100 by 856, we get 3 with a remainder of 532.
The next digit of our result is 3. 
Result so far: 45645.53
If we take 2568 away from 3100, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 11:
5320 divided by 856 is 6 with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 45645.536
If we take 5136 away from 5320, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
1840 divided by 856 is 2 with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 45645.5362
Subtracting 1712 from 1840 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 13:
If we divide 1280 by 856, we get 1 and a remainder of 424.
Write down 1 as next digit of the result. 
Result so far: 45645.53621
Subtract 856 from 1280 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 14:
856 goes into 4240 4 times with a remainder of 816.
Write down 4 as next digit of the result. 
Result so far: 45645.536214
The remainder is 816 after subtracting 3424 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Advancing to step 15:
When dividing 8160 by 856, we get 9 with a remainder of 456.
The number 9 becomes the next digit in our result. 
Result so far: 45645.5362149
Subtracting 7704 from 8160 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 16:
If we divide 4560 by 856, we get 5 and a remainder of 280.
The next digit of our result is 5. 
Result so far: 45645.53621495
Subtracting 4280 from 4560 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 45645.53621495, with a leftover of 2.8e-07.
