We're dividing 856941 by 20 
Our goal is to divide 856941 by 20.

On to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 20

Advancing to step 2:
20 can be fit into 85 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 80 away from 85, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 20

Moving on to step 3:
20 goes into 56 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 40 from 56 and we're left with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 20

Advancing to step 4:
169 divided by 20 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 428.0
Deduct 160 from 169 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 20

Going ahead to step 5:
When dividing 94 by 20, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4284.0
If we take 80 away from 94, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 20

Going ahead to step 6:
The number 20 fits into 141 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 42847.0
If we subtract 140 from 141, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
20 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 42847.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 42847.05
Deduct 100 from 100 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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42847.05
If we subtract 0 from 0, we 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.

Step 10:
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: 42847.05
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.

The quotient of the division is 42847.05, and the remainder is 0.0.
