Let's divide 846439 by 87
We want to divide 846439 by 87.

Step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 87

On to step 2:
When dividing 84 by 87, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 87

On to step 3:
87 goes into 846 9 times with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 783 from 846 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 87

Advancing to step 4:
634 divided by 87 is 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 609 from 634 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 87

Advancing to step 5:
253 divided by 87 is 2 with a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 972.0
If we take 174 away from 253, we end up with 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 87

Moving on to step 6:
799 divided by 87 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 9729.0
If we take 783 away from 799, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 87, we get 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 9729.1
The remainder is 73 after subtracting 87 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
When dividing 730 by 87, we get 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 9729.18
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
When dividing 340 by 87, we get 3 with a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 9729.183
Subtract 261 from 340 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
87 goes into 790 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 9729.1839
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
87 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 9729.1839
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
700 divided by 87 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 9729.183908
If we take 696 away from 700, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
87 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9729.183908
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
87 goes into 400 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 9729.18390804
The remainder is 52 after subtracting 348 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 9729.18390804, and the remainder is 5.2e-08.
