We divide 639794 by 87
We want to divide 639794 by 87.

Let's proceed to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 87

On to step 2:
When dividing 63 by 87, we get 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 87

On to step 3:
639 divided by 87 is 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 609 from 639 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 87

Advancing to step 4:
87 goes into 307 3 times with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 261 away from 307, we end up with 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 87

Step 5:
87 goes into 469 5 times with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 735.0
If we subtract 435 from 469, we get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 87

Moving on to step 6:
The number 87 fits into 344 3 times, leaving a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 7353.0
The remainder is 83 after subtracting 261 from 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 7:
If we divide 830 by 87, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 7353.9
Deduct 783 from 830 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
The number 87 fits into 470 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7353.95
The remainder is 35 after subtracting 435 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
87 can be fit into 350 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 7353.954
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 87, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7353.954
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
87 goes into 200 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 7353.95402
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
If we divide 260 by 87, we get 2 and a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 7353.954022
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 7353.954022 and a remainder of 8.6e-06.
