Let's divide 851668 by 5
We're looking to find how many times 5 goes into 851668.

Moving on to step 1:
8 divided by 5 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 5 from 8 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 5

Moving on to step 2:
35 divided by 5 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 35 away from 35, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 5

Let's proceed to step 3:
When dividing 1 by 5, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 5

On to step 4:
If we divide 16 by 5, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1703.0
Subtract 15 from 16 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 5

On to step 5:
When dividing 16 by 5, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 17033.0
The remainder is 1 after subtracting 15 from 16.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 5

Going ahead to step 6:
18 divided by 5 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 170333.0
The remainder is 3 after subtracting 15 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 5 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 170333.6
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 170333.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 170333.6
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 170333.6 with a balance of 0.0.
