740983 ÷ 86 
We're looking to find how many times 86 goes into 740983.

On to step 1:
If we divide 7 by 86, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 86

Going ahead to step 2:
If we divide 74 by 86, we get 0 and a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 86

Let's proceed to step 3:
740 divided by 86 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 688 from 740 and we're left with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 86

On to step 4:
529 divided by 86 is 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 516 from 529 leaves us with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 86

Moving on to step 5:
86 goes into 138 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 861.0
If we subtract 86 from 138, we get 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 86

Going ahead to step 6:
When dividing 523 by 86, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 8616.0
If we subtract 516 from 523, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
86 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 8616.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
86 goes into 700 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8616.08
If we take 688 away from 700, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 8616.081
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
If we divide 340 by 86, we get 3 and a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 8616.0813
If we take 258 away from 340, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 11:
If we divide 820 by 86, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 8616.08139
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 12:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 8616.081395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
If we divide 300 by 86, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 8616.0813953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 8616.08139534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 8616.08139534, with a leftover of 7.6e-08.
