We divide 639829 by 87
We want to divide 639829 by 87.

Going ahead to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 87

Advancing to step 2:
The number 87 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 87

Moving on to step 3:
87 can be fit into 639 7 times, resulting in a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 609 away from 639, we end up with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 87

Moving on to step 4:
When dividing 308 by 87, we get 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 261 from 308, we get 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 87

Let's proceed to step 5:
87 goes into 472 5 times with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 735.0
If we subtract 435 from 472, we get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 87

Going ahead to step 6:
87 goes into 379 4 times with a remainder of 31.
The next digit of our result is 4. 
Result so far: 7354.0
If we take 348 away from 379, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 87 fits into 310 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 7354.3
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
87 goes into 490 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 7354.35
Subtract 435 from 490 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
If we divide 550 by 87, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 7354.356
Deduct 522 from 550 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 7354.3563
The remainder is 19 after subtracting 261 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
If we divide 190 by 87, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7354.35632
Subtracting 174 from 190 leaves us 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.

Step 12:
87 goes into 160 1 times with a remainder of 73.
The next digit of our result is 1. 
Result so far: 7354.356321
Subtract 87 from 160 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 13:
When dividing 730 by 87, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 7354.3563218
If we subtract 696 from 730, we 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.

Going ahead to step 14:
87 can be fit into 340 3 times, resulting in a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 7354.35632183
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The quotient of the division is 7354.35632183, and the remainder is 7.9e-08.
