Let's divide 74739654 by 840
Our goal is to divide 74739654 by 840.

Going ahead to step 1:
840 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 840

Let's proceed to step 2:
840 can be fit into 74 0 times, resulting in a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 840

Advancing to step 3:
When dividing 747 by 840, we get 0 with a remainder of 747.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 747 to get 747.
Include the next digit (3) from the dividend after 747, then repeat: 7473 / 840

Step 4:
840 goes into 7473 8 times with a remainder of 753.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 6720 from 7473 to get 753.
Take the next digit (9) from the dividend and append it to 753, then repeat: 7539 / 840

Going ahead to step 5:
7539 divided by 840 is 8 with a remainder of 819.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 6720 from 7539 to get 819.
Append the next digit (6) from the dividend to 819 and continue with: 8196 / 840

Moving on to step 6:
The number 840 fits into 8196 9 times, leaving a remainder of 636.
Put 9 as the next digit of the answer. 
Result so far: 889.0
If we take 7560 away from 8196, we end up with 636.
Append the next digit (5) from the dividend to 636 and continue with: 6365 / 840

Advancing to step 7:
840 can be fit into 6365 7 times, resulting in a remainder of 485.
The number 7 becomes the next digit in our result. 
Result so far: 8897.0
If we take 5880 away from 6365, we end up with 485.
Append the next digit (4) from the dividend to 485 and continue with: 4854 / 840

Step 8:
4854 divided by 840 is 5 with a remainder of 654.
Write down 5 as next digit of the result. 
Result so far: 88975.0
The remainder is 654 after subtracting 4200 from 4854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 9:
The number 840 fits into 6540 7 times, leaving a remainder of 660.
The number 7 becomes the next digit in our result. 
Result so far: 88975.7
Deduct 5880 from 6540 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 10:
840 goes into 6600 7 times with a remainder of 720.
The number 7 becomes the next digit in our result. 
Result so far: 88975.77
Subtract 5880 from 6600 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final outcome is 88975.77, with a leftover of 0.72.
