Let's divide 669676 by 858
Our goal is to divide 669676 by 858.

Going ahead to step 1:
When dividing 6 by 858, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 858

Going ahead to step 2:
858 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 858

Step 3:
When dividing 669 by 858, we get 0 with a remainder of 669.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 669 and we're left with 669.
Take the next digit (6) from the dividend and append it to 669, then repeat: 6696 / 858

Going ahead to step 4:
If we divide 6696 by 858, we get 7 and a remainder of 690.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6006 away from 6696, we end up with 690.
Include the next digit (7) from the dividend after 690, then repeat: 6907 / 858

Step 5:
The number 858 fits into 6907 8 times, leaving a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 6864 from 6907 and we're left with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 858

Advancing to step 6:
858 goes into 436 0 times with a remainder of 436.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtract 0 from 436 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 7:
4360 divided by 858 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 780.5
The remainder is 70 after subtracting 4290 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
If we divide 700 by 858, we get 0 and a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 780.5
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 9:
When dividing 7000 by 858, we get 8 with a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 780.508
If we subtract 6864 from 7000, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
The number 858 fits into 1360 1 times, leaving a remainder of 502.
Record the quotient 1 as the next digit in the result. 
Result so far: 780.5081
The remainder is 502 after subtracting 858 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 11:
The number 858 fits into 5020 5 times, leaving a remainder of 730.
The number 5 becomes the next digit in our result. 
Result so far: 780.50815
Subtract 4290 from 5020 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 12:
858 can be fit into 7300 8 times, resulting in a remainder of 436.
Use 8 as the next digit of our solution. 
Result so far: 780.508158
If we take 6864 away from 7300, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 13:
858 goes into 4360 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 780.5081585
Subtracting 4290 from 4360 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
700 divided by 858 is 0 with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 780.5081585
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 780.5081585, with a leftover of 7e-07.
