We divide 78155153 by 86
We're looking to find how many times 86 goes into 78155153.

Step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 86

Going ahead to step 2:
When dividing 78 by 86, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 86

Step 3:
86 can be fit into 781 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 7 after subtracting 774 from 781.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 86

Moving on to step 4:
86 goes into 75 0 times with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 86

Moving on to step 5:
86 goes into 755 8 times with a remainder of 67.
The next digit of our result is 8. 
Result so far: 908.0
Deduct 688 from 755 and we're left with 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 86

Moving on to step 6:
86 can be fit into 671 7 times, resulting in a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 9087.0
If we subtract 602 from 671, we get 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 86

Let's proceed to step 7:
The number 86 fits into 695 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 90878.0
Deduct 688 from 695 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 86

Let's proceed to step 8:
86 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 908780.0
If we take 0 away from 73, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
86 can be fit into 730 8 times, resulting in a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 908780.8
If we take 688 away from 730, 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.

Moving on to step 10:
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: 908780.84
Subtracting 344 from 420 leaves us 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.

Moving on to step 11:
When dividing 760 by 86, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 908780.848
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
The number 86 fits into 720 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 908780.8488
If we subtract 688 from 720, we get 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 quotient of the division is 908780.8488, and the remainder is 0.00032.
