We look at the division of 86074090 by 712 
We're looking to find how many times 712 goes into 86074090.

Step 1:
When dividing 8 by 712, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 712

Step 2:
712 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (0) from the dividend after 86, then repeat: 860 / 712

Moving on to step 3:
The number 712 fits into 860 1 times, leaving a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 148 after subtracting 712 from 860.
Include the next digit (7) from the dividend after 148, then repeat: 1487 / 712

Advancing to step 4:
712 can be fit into 1487 2 times, resulting in a remainder of 63.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1424 from 1487 and we're left with 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 712

Advancing to step 5:
If we divide 634 by 712, we get 0 and a remainder of 634.
The next digit of our result is 0. 
Result so far: 120.0
If we subtract 0 from 634, we get 634.
Include the next digit (0) from the dividend after 634, then repeat: 6340 / 712

Going ahead to step 6:
712 goes into 6340 8 times with a remainder of 644.
The next digit of our result is 8. 
Result so far: 1208.0
Subtracting 5696 from 6340 leaves us with 644.
Include the next digit (9) from the dividend after 644, then repeat: 6449 / 712

Advancing to step 7:
712 can be fit into 6449 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 12089.0
If we subtract 6408 from 6449, we get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 712

Let's proceed to step 8:
If we divide 410 by 712, we get 0 and a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 120890.0
Deduct 0 from 410 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 9:
4100 divided by 712 is 5 with a remainder of 540.
The next digit of our result is 5. 
Result so far: 120890.5
Deduct 3560 from 4100 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 10:
The number 712 fits into 5400 7 times, leaving a remainder of 416.
The number 7 becomes the next digit in our result. 
Result so far: 120890.57
If we take 4984 away from 5400, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 11:
4160 divided by 712 is 5 with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 120890.575
Subtracting 3560 from 4160 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 12:
When dividing 6000 by 712, we get 8 with a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 120890.5758
Subtracting 5696 from 6000 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
712 can be fit into 3040 4 times, resulting in a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 120890.57584
The remainder is 192 after subtracting 2848 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
712 can be fit into 1920 2 times, resulting in a remainder of 496.
Record the quotient 2 as the next digit in the result. 
Result so far: 120890.575842
Subtracting 1424 from 1920 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
712 can be fit into 4960 6 times, resulting in a remainder of 688.
Write down 6 as next digit of the result. 
Result so far: 120890.5758426
Subtracting 4272 from 4960 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 16:
The number 712 fits into 6880 9 times, leaving a remainder of 472.
The next digit of our result is 9. 
Result so far: 120890.57584269
Subtracting 6408 from 6880 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

After the division, we end up with 120890.57584269 and a remainder of 4.72e-07.
