742264 divided by 86 
We want to figure out the number of times 742264 can be divided by 86.

On to step 1:
7 divided by 86 is 0 with a remainder of 7.
Write down 0 as next digit of the 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

Step 2:
74 divided by 86 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 86

On to step 3:
When dividing 742 by 86, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 688 from 742 leaves us with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 86

Step 4:
86 goes into 542 6 times with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 26 after subtracting 516 from 542.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 86

On to step 5:
When dividing 266 by 86, we get 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 863.0
Subtracting 258 from 266 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 86

On to step 6:
86 can be fit into 84 0 times, resulting in a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 8630.0
The remainder is 84 after subtracting 0 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
86 goes into 840 9 times with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 8630.9
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
When dividing 660 by 86, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 8630.97
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
When dividing 580 by 86, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 8630.976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
When dividing 640 by 86, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 8630.9767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 8630.97674
If we take 344 away from 380, we end up 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.

Let's proceed to step 12:
86 goes into 360 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 8630.976744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 8630.976744 and a remainder of 1.6e-06.
