Let's divide 86116987 by 154
We want to figure out the number of times 86116987 can be divided by 154.

On to step 1:
If we divide 8 by 154, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 154

Let's proceed to step 2:
When dividing 86 by 154, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 154

On to step 3:
154 goes into 861 5 times with a remainder of 91.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 770 from 861 leaves us with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 154

Going ahead to step 4:
154 goes into 911 5 times with a remainder of 141.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 770 from 911 leaves us with 141.
Append the next digit (6) from the dividend to 141 and continue with: 1416 / 154

Going ahead to step 5:
If we divide 1416 by 154, we get 9 and a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 559.0
If we subtract 1386 from 1416, we get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 154

Step 6:
When dividing 309 by 154, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 5592.0
The remainder is 1 after subtracting 308 from 309.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 154

Advancing to step 7:
When dividing 18 by 154, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 55920.0
Subtract 0 from 18 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 154

Going ahead to step 8:
154 goes into 187 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 559201.0
The remainder is 33 after subtracting 154 from 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 9:
154 goes into 330 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 559201.2
Subtract 308 from 330 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
If we divide 220 by 154, we get 1 and a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 559201.21
Subtract 154 from 220 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
If we divide 660 by 154, we get 4 and a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 559201.214
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
154 goes into 440 2 times with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 559201.2142
If we subtract 308 from 440, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
154 can be fit into 1320 8 times, resulting in a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 559201.21428
Subtract 1232 from 1320 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
If we divide 880 by 154, we get 5 and a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 559201.214285
If we subtract 770 from 880, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 15:
154 goes into 1100 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 559201.2142857
If we take 1078 away from 1100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
The number 154 fits into 220 1 times, leaving a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 559201.21428571
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 559201.21428571 with a remainder of 6.6e-08.
