We're dividing 86436078 by 174 
We want to divide 86436078 by 174.

Let's proceed to step 1:
When dividing 8 by 174, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 174

Moving on to step 2:
The number 174 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 174

Moving on to step 3:
The number 174 fits into 864 4 times, leaving a remainder of 168.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 696 from 864 leaves us with 168.
Grab the next digit (3) from the dividend, add it to 168, then carry on: 1683 / 174

On to step 4:
1683 divided by 174 is 9 with a remainder of 117.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 1566 from 1683 and we're left with 117.
Grab the next digit (6) from the dividend, add it to 117, then carry on: 1176 / 174

Advancing to step 5:
If we divide 1176 by 174, we get 6 and a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 496.0
Subtract 1044 from 1176 to get 132.
Include the next digit (0) from the dividend after 132, then repeat: 1320 / 174

Advancing to step 6:
1320 divided by 174 is 7 with a remainder of 102.
The next digit of our result is 7. 
Result so far: 4967.0
If we subtract 1218 from 1320, we get 102.
Take the next digit (7) from the dividend and append it to 102, then repeat: 1027 / 174

Going ahead to step 7:
174 goes into 1027 5 times with a remainder of 157.
The next digit of our result is 5. 
Result so far: 49675.0
Subtracting 870 from 1027 leaves us with 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 174

Let's proceed to step 8:
1578 divided by 174 is 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 496759.0
If we take 1566 away from 1578, 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.

Let's proceed to step 9:
174 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 496759.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
When dividing 1200 by 174, we get 6 with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 496759.06
Deduct 1044 from 1200 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
When dividing 1560 by 174, we get 8 with a remainder of 168.
Use 8 as the next digit of our solution. 
Result so far: 496759.068
If we take 1392 away from 1560, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
1680 divided by 174 is 9 with a remainder of 114.
The next digit of our result is 9. 
Result so far: 496759.0689
The remainder is 114 after subtracting 1566 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 13:
If we divide 1140 by 174, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 496759.06896
If we subtract 1044 from 1140, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 14:
If we divide 960 by 174, we get 5 and a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 496759.068965
The remainder is 90 after subtracting 870 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
If we divide 900 by 174, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 496759.0689655
If we subtract 870 from 900, we 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.

The final outcome is 496759.0689655, with a leftover of 3e-07.
