We're dividing 749840 by 84 
Our goal is to divide 749840 by 84.

Step 1:
When dividing 7 by 84, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 84

On to step 2:
84 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 84

Advancing to step 3:
84 can be fit into 749 8 times, resulting in a remainder of 77.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 672 from 749 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 84

Moving on to step 4:
The number 84 fits into 778 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 756 from 778 and we're left with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 84

On to step 5:
224 divided by 84 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 892.0
Subtract 168 from 224 to get 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 84

On to step 6:
If we divide 560 by 84, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 8926.0
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
The number 84 fits into 560 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 8926.6
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
If we divide 560 by 84, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 8926.66
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 8926.66 with a balance of 0.056.
