20099047 divided by 840 
We want to divide 20099047 by 840.

Step 1:
If we divide 2 by 840, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 840

Advancing to step 2:
840 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 840

Step 3:
The number 840 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 200 and we're left with 200.
Append the next digit (9) from the dividend to 200 and continue with: 2009 / 840

Advancing to step 4:
If we divide 2009 by 840, we get 2 and a remainder of 329.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1680 from 2009, we get 329.
Grab the next digit (9) from the dividend, add it to 329, then carry on: 3299 / 840

Let's proceed to step 5:
840 goes into 3299 3 times with a remainder of 779.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 779 after subtracting 2520 from 3299.
Take the next digit (0) from the dividend and append it to 779, then repeat: 7790 / 840

Moving on to step 6:
840 goes into 7790 9 times with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 239.0
Deduct 7560 from 7790 and we're left with 230.
Grab the next digit (4) from the dividend, add it to 230, then carry on: 2304 / 840

Advancing to step 7:
840 goes into 2304 2 times with a remainder of 624.
Write down 2 as next digit of the result. 
Result so far: 2392.0
Deduct 1680 from 2304 and we're left with 624.
Grab the next digit (7) from the dividend, add it to 624, then carry on: 6247 / 840

Let's proceed to step 8:
The number 840 fits into 6247 7 times, leaving a remainder of 367.
Record the quotient 7 as the next digit in the result. 
Result so far: 23927.0
Deduct 5880 from 6247 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 9:
840 can be fit into 3670 4 times, resulting in a remainder of 310.
Use 4 as the next digit of our solution. 
Result so far: 23927.4
Subtract 3360 from 3670 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
3100 divided by 840 is 3 with a remainder of 580.
Record the quotient 3 as the next digit in the result. 
Result so far: 23927.43
Subtracting 2520 from 3100 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
840 can be fit into 5800 6 times, resulting in a remainder of 760.
The number 6 becomes the next digit in our result. 
Result so far: 23927.436
If we subtract 5040 from 5800, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 12:
840 can be fit into 7600 9 times, resulting in a remainder of 40.
The next digit of our result is 9. 
Result so far: 23927.4369
Subtracting 7560 from 7600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
When dividing 400 by 840, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 23927.4369
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 14:
If we divide 4000 by 840, we get 4 and a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 23927.436904
Subtract 3360 from 4000 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 15:
6400 divided by 840 is 7 with a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 23927.4369047
Subtracting 5880 from 6400 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 16:
5200 divided by 840 is 6 with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 23927.43690476
Subtracting 5040 from 5200 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 23927.43690476, with a leftover of 1.6e-07.
