Let's divide 857970 by 20
We want to divide 857970 by 20.

Let's proceed to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 20

Going ahead to step 2:
When dividing 85 by 20, we get 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 80 from 85 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 20

On to step 3:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 40 from 57 and we're left with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 20

Step 4:
When dividing 179 by 20, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 428.0
The remainder is 19 after subtracting 160 from 179.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 20

Advancing to step 5:
If we divide 197 by 20, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 4289.0
Subtracting 180 from 197 leaves us with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 20

Step 6:
20 goes into 170 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 42898.0
Subtracting 160 from 170 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 42898.5
Subtracting 100 from 100 leaves us 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42898.5
If we take 0 away from 0, 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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42898.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 42898.5, with a leftover of 0.0.
