851714 divided by 20 
We want to figure out the number of times 851714 can be divided by 20.

Going ahead to step 1:
8 divided by 20 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 20

Moving on to step 2:
85 divided by 20 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 80 from 85, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 20

Going ahead to step 3:
20 can be fit into 51 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 40 from 51 leaves us with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 20

Advancing to step 4:
The number 20 fits into 117 5 times, leaving a remainder of 17.
The next digit of our result is 5. 
Result so far: 425.0
The remainder is 17 after subtracting 100 from 117.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 20

Moving on to step 5:
If we divide 171 by 20, we get 8 and a remainder of 11.
The next digit of our result is 8. 
Result so far: 4258.0
If we take 160 away from 171, we end up with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 20

Advancing to step 6:
114 divided by 20 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 42585.0
If we take 100 away from 114, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
140 divided by 20 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 42585.7
If we take 140 away from 140, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 42585.7
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 42585.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 42585.7 with a remaining 0.0.
