We're dividing 664629 by 87 
Let's see how many times 87 fits into 664629.

Advancing to step 1:
87 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 87

Advancing to step 2:
87 can be fit into 66 0 times, resulting in a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 87

Step 3:
If we divide 664 by 87, we get 7 and a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 609 from 664, we get 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 87

On to step 4:
The number 87 fits into 556 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 34 after subtracting 522 from 556.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 87

Let's proceed to step 5:
87 can be fit into 342 3 times, resulting in a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 763.0
If we subtract 261 from 342, we get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 87

Going ahead to step 6:
When dividing 819 by 87, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 7639.0
If we take 783 away from 819, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 87 fits into 360 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 7639.4
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 87, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 7639.41
If we take 87 away from 120, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
When dividing 330 by 87, we get 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 7639.413
Subtracting 261 from 330 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
690 divided by 87 is 7 with a remainder of 81.
The next digit of our result is 7. 
Result so far: 7639.4137
Subtract 609 from 690 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 11:
If we divide 810 by 87, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 7639.41379
Deduct 783 from 810 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
If we divide 270 by 87, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 7639.413793
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
90 divided by 87 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 7639.4137931
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
When dividing 30 by 87, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7639.4137931
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 7639.4137931 with a balance of 3e-08.
