Let's divide 74387692 by 840
We're looking to find how many times 840 goes into 74387692.

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

Advancing to step 2:
When dividing 74 by 840, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 840

Let's proceed to step 3:
840 goes into 743 0 times with a remainder of 743.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 743, we get 743.
Grab the next digit (8) from the dividend, add it to 743, then carry on: 7438 / 840

Moving on to step 4:
When dividing 7438 by 840, we get 8 with a remainder of 718.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6720 from 7438, we get 718.
Fetch the next digit (7) from the dividend, attach it to 718 and continue: 7187 / 840

Advancing to step 5:
7187 divided by 840 is 8 with a remainder of 467.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 6720 from 7187 to get 467.
Include the next digit (6) from the dividend after 467, then repeat: 4676 / 840

Let's proceed to step 6:
If we divide 4676 by 840, we get 5 and a remainder of 476.
Use 5 as the next digit of our solution. 
Result so far: 885.0
Subtract 4200 from 4676 to get 476.
Fetch the next digit (9) from the dividend, attach it to 476 and continue: 4769 / 840

Moving on to step 7:
4769 divided by 840 is 5 with a remainder of 569.
Put 5 as the next digit of the answer. 
Result so far: 8855.0
Subtracting 4200 from 4769 leaves us with 569.
Include the next digit (2) from the dividend after 569, then repeat: 5692 / 840

On to step 8:
When dividing 5692 by 840, we get 6 with a remainder of 652.
Put 6 as the next digit of the answer. 
Result so far: 88556.0
Deduct 5040 from 5692 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 9:
840 can be fit into 6520 7 times, resulting in a remainder of 640.
Put 7 as the next digit of the answer. 
Result so far: 88556.7
Subtract 5880 from 6520 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.

On to step 10:
The number 840 fits into 6400 7 times, leaving a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 88556.77
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.

The final result is 88556.77 with a remainder of 0.52.
