669085 ÷ 87 
We want to divide 669085 by 87.

Step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
The next digit of our result is 0. 
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

Going ahead to step 2:
If we divide 66 by 87, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 87

Step 3:
87 goes into 669 7 times with a remainder of 60.
The next digit of our result is 7. 
Result so far: 7.0
If we take 609 away from 669, we end up with 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 87

On to step 4:
87 goes into 600 6 times with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 76.0
If we subtract 522 from 600, we get 78.
Take the next digit (8) from the dividend and append it to 78, then repeat: 788 / 87

Going ahead to step 5:
The number 87 fits into 788 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 769.0
If we subtract 783 from 788, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 87

Step 6:
When dividing 55 by 87, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 7690.0
Deduct 0 from 55 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
550 divided by 87 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 7690.6
Subtracting 522 from 550 leaves us 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.

Moving on to step 8:
If we divide 280 by 87, we get 3 and a remainder of 19.
The next digit of our result is 3. 
Result so far: 7690.63
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 7690.632
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 87 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 7690.6321
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.

Advancing to step 11:
87 goes into 730 8 times with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 7690.63218
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.

On to step 12:
If we divide 340 by 87, we get 3 and a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 7690.632183
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.

Moving on to step 13:
If we divide 790 by 87, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 7690.6321839
Subtracting 783 from 790 leaves us with 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 14:
87 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7690.6321839
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7690.6321839, with a leftover of 7e-08.
