We look at the division of 15377650 by 86 
Let's see how many times 86 fits into 15377650.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 86

Going ahead to step 2:
If we divide 15 by 86, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 86

On to step 3:
86 goes into 153 1 times with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 86 away from 153, we end up with 67.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 86

Let's proceed to step 4:
The number 86 fits into 677 7 times, leaving a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 602 from 677 leaves us with 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 86

Moving on to step 5:
86 can be fit into 757 8 times, resulting in a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
If we take 688 away from 757, we end up with 69.
Append the next digit (6) from the dividend to 69 and continue with: 696 / 86

Let's proceed to step 6:
86 can be fit into 696 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1788.0
If we subtract 688 from 696, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 86

Let's proceed to step 7:
86 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 17880.0
Subtract 0 from 85 to get 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 86

Advancing to step 8:
850 divided by 86 is 9 with a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 178809.0
Subtract 774 from 850 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 178809.8
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
86 goes into 720 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 178809.88
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 178809.88, with a leftover of 0.032.
