Let's divide 19337760 by 840
Our goal is to divide 19337760 by 840.

On to step 1:
The number 840 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 840

Step 2:
840 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 840

Advancing to step 3:
The number 840 fits into 193 0 times, leaving a remainder of 193.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 193 after subtracting 0 from 193.
Grab the next digit (3) from the dividend, add it to 193, then carry on: 1933 / 840

Going ahead to step 4:
1933 divided by 840 is 2 with a remainder of 253.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 253 after subtracting 1680 from 1933.
Append the next digit (7) from the dividend to 253 and continue with: 2537 / 840

Going ahead to step 5:
2537 divided by 840 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 2520 from 2537 and we're left with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 840

Advancing to step 6:
840 can be fit into 177 0 times, resulting in a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 230.0
If we take 0 away from 177, we end up with 177.
Grab the next digit (6) from the dividend, add it to 177, then carry on: 1776 / 840

Step 7:
When dividing 1776 by 840, we get 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 2302.0
Deduct 1680 from 1776 and we're left with 96.
Grab the next digit (0) from the dividend, add it to 96, then carry on: 960 / 840

Advancing to step 8:
840 goes into 960 1 times with a remainder of 120.
Write down 1 as next digit of the result. 
Result so far: 23021.0
Subtracting 840 from 960 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 9:
840 can be fit into 1200 1 times, resulting in a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 23021.1
If we subtract 840 from 1200, we 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.

Moving on to step 10:
When dividing 3600 by 840, we get 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 23021.14
If we take 3360 away from 3600, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
840 goes into 2400 2 times with a remainder of 720.
Use 2 as the next digit of our solution. 
Result so far: 23021.142
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.

Step 12:
840 goes into 7200 8 times with a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 23021.1428
Subtracting 6720 from 7200 leaves us 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.

Advancing 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: 23021.14285
Subtract 4200 from 4800 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 14:
If we divide 6000 by 840, we get 7 and a remainder of 120.
The next digit of our result is 7. 
Result so far: 23021.142857
If we take 5880 away from 6000, we end up with 120.
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:
840 can be fit into 1200 1 times, resulting in a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 23021.1428571
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.

Advancing to step 16:
The number 840 fits into 3600 4 times, leaving a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 23021.14285714
Subtracting 3360 from 3600 leaves us with 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 result is 23021.14285714 with a remainder of 2.4e-07.
