We divide 20078924 by 858
We want to divide 20078924 by 858.

Advancing to step 1:
858 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 858

Let's proceed to step 2:
858 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 858

Moving on to step 3:
858 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 200 leaves us with 200.
Include the next digit (7) from the dividend after 200, then repeat: 2007 / 858

Going ahead to step 4:
If we divide 2007 by 858, we get 2 and a remainder of 291.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1716 from 2007 and we're left with 291.
Fetch the next digit (8) from the dividend, attach it to 291 and continue: 2918 / 858

Advancing to step 5:
The number 858 fits into 2918 3 times, leaving a remainder of 344.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2574 from 2918, we get 344.
Bring next digit (9) of the dividend behind the 344 and repeat the process: 3449 / 858

On to step 6:
When dividing 3449 by 858, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 234.0
Subtracting 3432 from 3449 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 858

On to step 7:
172 divided by 858 is 0 with a remainder of 172.
The next digit of our result is 0. 
Result so far: 2340.0
If we subtract 0 from 172, we get 172.
Append the next digit (4) from the dividend to 172 and continue with: 1724 / 858

Advancing to step 8:
When dividing 1724 by 858, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 23402.0
Subtract 1716 from 1724 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
858 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 23402.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
If we divide 800 by 858, we get 0 and a remainder of 800.
The next digit of our result is 0. 
Result so far: 23402.0
Subtract 0 from 800 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 23402.0 and a remainder of 0.8.
