Let's divide 86389895 by 867
We want to figure out the number of times 86389895 can be divided by 867.

Advancing to step 1:
8 divided by 867 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 867

Going ahead to step 2:
867 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 867

Step 3:
867 goes into 863 0 times with a remainder of 863.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 863 to get 863.
Take the next digit (8) from the dividend and append it to 863, then repeat: 8638 / 867

Let's proceed to step 4:
When dividing 8638 by 867, we get 9 with a remainder of 835.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7803 away from 8638, we end up with 835.
Grab the next digit (9) from the dividend, add it to 835, then carry on: 8359 / 867

Advancing to step 5:
867 can be fit into 8359 9 times, resulting in a remainder of 556.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 7803 from 8359 to get 556.
Grab the next digit (8) from the dividend, add it to 556, then carry on: 5568 / 867

Going ahead to step 6:
If we divide 5568 by 867, we get 6 and a remainder of 366.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
The remainder is 366 after subtracting 5202 from 5568.
Take the next digit (9) from the dividend and append it to 366, then repeat: 3669 / 867

Going ahead to step 7:
867 can be fit into 3669 4 times, resulting in a remainder of 201.
The next digit of our result is 4. 
Result so far: 9964.0
Subtract 3468 from 3669 to get 201.
Append the next digit (5) from the dividend to 201 and continue with: 2015 / 867

Advancing to step 8:
The number 867 fits into 2015 2 times, leaving a remainder of 281.
Write down 2 as next digit of the result. 
Result so far: 99642.0
Subtract 1734 from 2015 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 9:
The number 867 fits into 2810 3 times, leaving a remainder of 209.
Use 3 as the next digit of our solution. 
Result so far: 99642.3
Subtracting 2601 from 2810 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 10:
867 goes into 2090 2 times with a remainder of 356.
Write down 2 as next digit of the result. 
Result so far: 99642.32
Subtract 1734 from 2090 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
The number 867 fits into 3560 4 times, leaving a remainder of 92.
The next digit of our result is 4. 
Result so far: 99642.324
Deduct 3468 from 3560 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 12:
The number 867 fits into 920 1 times, leaving a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 99642.3241
The remainder is 53 after subtracting 867 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 13:
When dividing 530 by 867, we get 0 with a remainder of 530.
Use 0 as the next digit of our solution. 
Result so far: 99642.3241
If we subtract 0 from 530, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 14:
When dividing 5300 by 867, we get 6 with a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 99642.324106
If we take 5202 away from 5300, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 15:
867 goes into 980 1 times with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 99642.3241061
Deduct 867 from 980 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 16:
The number 867 fits into 1130 1 times, leaving a remainder of 263.
The next digit of our result is 1. 
Result so far: 99642.32410611
The remainder is 263 after subtracting 867 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final outcome is 99642.32410611, with a leftover of 2.63e-07.
