We look at the division of 74400516 by 840 
Our goal is to divide 74400516 by 840.

Step 1:
The number 840 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 840

Going ahead to step 2:
840 can be fit into 74 0 times, resulting in a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 840

On to step 3:
840 goes into 744 0 times with a remainder of 744.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 744 to get 744.
Include the next digit (0) from the dividend after 744, then repeat: 7440 / 840

Going ahead to step 4:
7440 divided by 840 is 8 with a remainder of 720.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6720 from 7440 and we're left with 720.
Take the next digit (0) from the dividend and append it to 720, then repeat: 7200 / 840

Step 5:
7200 divided by 840 is 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 88.0
Subtract 6720 from 7200 to get 480.
Grab the next digit (5) from the dividend, add it to 480, then carry on: 4805 / 840

Moving on to step 6:
The number 840 fits into 4805 5 times, leaving a remainder of 605.
The number 5 becomes the next digit in our result. 
Result so far: 885.0
The remainder is 605 after subtracting 4200 from 4805.
Fetch the next digit (1) from the dividend, attach it to 605 and continue: 6051 / 840

Moving on to step 7:
840 goes into 6051 7 times with a remainder of 171.
Put 7 as the next digit of the answer. 
Result so far: 8857.0
If we take 5880 away from 6051, we end up with 171.
Bring next digit (6) of the dividend behind the 171 and repeat the process: 1716 / 840

Let's proceed to step 8:
1716 divided by 840 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 88572.0
Deduct 1680 from 1716 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
The number 840 fits into 360 0 times, leaving a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 88572.0
If we subtract 0 from 360, 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.

Going ahead to step 10:
3600 divided by 840 is 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 88572.04
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.

On to step 11:
If we divide 2400 by 840, we get 2 and a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 88572.042
Subtracting 1680 from 2400 leaves us 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 can be fit into 7200 8 times, resulting in a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 88572.0428
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.

Let's proceed to step 13:
840 can be fit into 4800 5 times, resulting in a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 88572.04285
If we subtract 4200 from 4800, we 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.

Going ahead to step 14:
840 goes into 6000 7 times with a remainder of 120.
The next digit of our result is 7. 
Result so far: 88572.042857
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.

On to step 15:
840 can be fit into 1200 1 times, resulting in a remainder of 360.
Write down 1 as next digit of the result. 
Result so far: 88572.0428571
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.

Going ahead to step 16:
When dividing 3600 by 840, we get 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 88572.04285714
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 quotient of the division is 88572.04285714, and the remainder is 2.4e-07.
