20914117 ÷ 840 
We want to divide 20914117 by 840.

Moving on to step 1:
2 divided by 840 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 840

Step 2:
The number 840 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 840

Step 3:
When dividing 209 by 840, we get 0 with a remainder of 209.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 209 after subtracting 0 from 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 840

Let's proceed to step 4:
2091 divided by 840 is 2 with a remainder of 411.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1680 from 2091 leaves us with 411.
Take the next digit (4) from the dividend and append it to 411, then repeat: 4114 / 840

On to step 5:
If we divide 4114 by 840, we get 4 and a remainder of 754.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 3360 away from 4114, we end up with 754.
Append the next digit (1) from the dividend to 754 and continue with: 7541 / 840

Let's proceed to step 6:
840 can be fit into 7541 8 times, resulting in a remainder of 821.
Put 8 as the next digit of the answer. 
Result so far: 248.0
The remainder is 821 after subtracting 6720 from 7541.
Fetch the next digit (1) from the dividend, attach it to 821 and continue: 8211 / 840

Advancing to step 7:
The number 840 fits into 8211 9 times, leaving a remainder of 651.
The next digit of our result is 9. 
Result so far: 2489.0
Subtract 7560 from 8211 to get 651.
Grab the next digit (7) from the dividend, add it to 651, then carry on: 6517 / 840

Step 8:
840 can be fit into 6517 7 times, resulting in a remainder of 637.
Put 7 as the next digit of the answer. 
Result so far: 24897.0
Subtract 5880 from 6517 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 9:
6370 divided by 840 is 7 with a remainder of 490.
Record the quotient 7 as the next digit in the result. 
Result so far: 24897.7
Deduct 5880 from 6370 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
When dividing 4900 by 840, we get 5 with a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 24897.75
The remainder is 700 after subtracting 4200 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
840 goes into 7000 8 times with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 24897.758
The remainder is 280 after subtracting 6720 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 12:
If we divide 2800 by 840, we get 3 and a remainder of 280.
Put 3 as the next digit of the answer. 
Result so far: 24897.7583
Deduct 2520 from 2800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
The number 840 fits into 2800 3 times, leaving a remainder of 280.
Write down 3 as next digit of the result. 
Result so far: 24897.75833
Deduct 2520 from 2800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 24897.75833 and a remainder of 0.00028.
