669446 ÷ 87 
We want to figure out the number of times 669446 can be divided by 87.

Going ahead to step 1:
When dividing 6 by 87, we get 0 with 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.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 87

Moving on to step 2:
If we divide 66 by 87, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 87

Moving on to step 3:
When dividing 669 by 87, we get 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 609 from 669, we get 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 87

Moving on to step 4:
87 can be fit into 604 6 times, resulting in a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtract 522 from 604 to get 82.
Bring next digit (4) of the dividend behind the 82 and repeat the process: 824 / 87

Moving on to step 5:
The number 87 fits into 824 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 769.0
If we subtract 783 from 824, we get 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 87

Advancing to step 6:
When dividing 416 by 87, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 7694.0
If we take 348 away from 416, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
87 can be fit into 680 7 times, resulting in a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 7694.7
Subtract 609 from 680 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 8:
87 can be fit into 710 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 7694.78
If we subtract 696 from 710, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
87 can be fit into 140 1 times, resulting in a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 7694.781
Deduct 87 from 140 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 10:
87 goes into 530 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 7694.7816
Deduct 522 from 530 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 87 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7694.7816
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
If we divide 800 by 87, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 7694.781609
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
When dividing 170 by 87, we get 1 with a remainder of 83.
The next digit of our result is 1. 
Result so far: 7694.7816091
If we take 87 away from 170, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 14:
If we divide 830 by 87, we get 9 and a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 7694.78160919
If we subtract 783 from 830, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 7694.78160919 with a remainder of 4.7e-08.
