21683922 divided by 840 
We want to divide 21683922 by 840.

Let's proceed to step 1:
When dividing 2 by 840, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 840

Step 2:
21 divided by 840 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 840

Let's proceed to step 3:
When dividing 216 by 840, we get 0 with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Bring next digit (8) of the dividend behind the 216 and repeat the process: 2168 / 840

Step 4:
840 goes into 2168 2 times with a remainder of 488.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1680 from 2168 to get 488.
Bring next digit (3) of the dividend behind the 488 and repeat the process: 4883 / 840

Let's proceed to step 5:
The number 840 fits into 4883 5 times, leaving a remainder of 683.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 4200 from 4883 leaves us with 683.
Fetch the next digit (9) from the dividend, attach it to 683 and continue: 6839 / 840

Advancing to step 6:
The number 840 fits into 6839 8 times, leaving a remainder of 119.
Put 8 as the next digit of the answer. 
Result so far: 258.0
If we take 6720 away from 6839, we end up with 119.
Take the next digit (2) from the dividend and append it to 119, then repeat: 1192 / 840

Going ahead to step 7:
840 can be fit into 1192 1 times, resulting in a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 2581.0
Subtract 840 from 1192 to get 352.
Append the next digit (2) from the dividend to 352 and continue with: 3522 / 840

Going ahead to step 8:
If we divide 3522 by 840, we get 4 and a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 25814.0
If we take 3360 away from 3522, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
When dividing 1620 by 840, we get 1 with a remainder of 780.
The next digit of our result is 1. 
Result so far: 25814.1
If we subtract 840 from 1620, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 10:
The number 840 fits into 7800 9 times, leaving a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 25814.19
The remainder is 240 after subtracting 7560 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
840 can be fit into 2400 2 times, resulting in a remainder of 720.
The next digit of our result is 2. 
Result so far: 25814.192
Deduct 1680 from 2400 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 12:
When dividing 7200 by 840, we get 8 with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 25814.1928
Deduct 6720 from 7200 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
If we divide 4800 by 840, we get 5 and a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 25814.19285
If we take 4200 away from 4800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
When dividing 6000 by 840, we get 7 with a remainder of 120.
The next digit of our result is 7. 
Result so far: 25814.192857
The remainder is 120 after subtracting 5880 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
1200 divided by 840 is 1 with a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 25814.1928571
Subtract 840 from 1200 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 16:
3600 divided by 840 is 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 25814.19285714
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 25814.19285714, with a leftover of 2.4e-07.
