We look at the division of 20780317 by 851 
We want to figure out the number of times 20780317 can be divided by 851.

On to step 1:
851 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 851

Going ahead to step 2:
If we divide 20 by 851, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 851

Going ahead to step 3:
207 divided by 851 is 0 with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 207 leaves us with 207.
Take the next digit (8) from the dividend and append it to 207, then repeat: 2078 / 851

Advancing to step 4:
851 goes into 2078 2 times with a remainder of 376.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 376 after subtracting 1702 from 2078.
Include the next digit (0) from the dividend after 376, then repeat: 3760 / 851

Moving on to step 5:
When dividing 3760 by 851, we get 4 with a remainder of 356.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 3404 away from 3760, we end up with 356.
Append the next digit (3) from the dividend to 356 and continue with: 3563 / 851

Moving on to step 6:
3563 divided by 851 is 4 with a remainder of 159.
The next digit of our result is 4. 
Result so far: 244.0
If we take 3404 away from 3563, we end up with 159.
Take the next digit (1) from the dividend and append it to 159, then repeat: 1591 / 851

On to step 7:
The number 851 fits into 1591 1 times, leaving a remainder of 740.
Use 1 as the next digit of our solution. 
Result so far: 2441.0
If we take 851 away from 1591, we end up with 740.
Grab the next digit (7) from the dividend, add it to 740, then carry on: 7407 / 851

Let's proceed to step 8:
The number 851 fits into 7407 8 times, leaving a remainder of 599.
Use 8 as the next digit of our solution. 
Result so far: 24418.0
Subtracting 6808 from 7407 leaves us with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

On to step 9:
If we divide 5990 by 851, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 24418.7
The remainder is 33 after subtracting 5957 from 5990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
851 can be fit into 330 0 times, resulting in a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 24418.7
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 11:
If we divide 3300 by 851, we get 3 and a remainder of 747.
The number 3 becomes the next digit in our result. 
Result so far: 24418.703
Subtracting 2553 from 3300 leaves us with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Let's proceed to step 12:
If we divide 7470 by 851, we get 8 and a remainder of 662.
Record the quotient 8 as the next digit in the result. 
Result so far: 24418.7038
If we subtract 6808 from 7470, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 13:
When dividing 6620 by 851, we get 7 with a remainder of 663.
The next digit of our result is 7. 
Result so far: 24418.70387
If we subtract 5957 from 6620, we get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 14:
If we divide 6630 by 851, we get 7 and a remainder of 673.
Put 7 as the next digit of the answer. 
Result so far: 24418.703877
If we subtract 5957 from 6630, we get 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

The quotient of the division is 24418.703877, and the remainder is 6.73e-05.
