Let's divide 861933 by 87
We're looking to find how many times 87 goes into 861933.

Advancing to step 1:
8 divided by 87 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 87

Step 2:
86 divided by 87 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 87

Step 3:
861 divided by 87 is 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 783 away from 861, we end up with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 87

Going ahead to step 4:
87 can be fit into 789 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 783 from 789 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 87

Step 5:
When dividing 63 by 87, we get 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 990.0
Subtract 0 from 63 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 87

On to step 6:
The number 87 fits into 633 7 times, leaving a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 9907.0
Subtracting 609 from 633 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
If we divide 240 by 87, we get 2 and a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 9907.2
If we take 174 away from 240, we end up 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.

Let's proceed to step 8:
87 can be fit into 660 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 9907.27
Subtracting 609 from 660 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
The number 87 fits into 510 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9907.275
Subtracting 435 from 510 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
The number 87 fits into 750 8 times, leaving a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 9907.2758
Subtract 696 from 750 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
When dividing 540 by 87, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 9907.27586
If we subtract 522 from 540, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 87 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 9907.275862
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
87 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 9907.275862
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
87 goes into 600 6 times with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 9907.27586206
Subtracting 522 from 600 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The quotient of the division is 9907.27586206, and the remainder is 7.8e-08.
