We look at the division of 851253 by 6 
We want to figure out the number of times 851253 can be divided by 6.

Let's proceed to step 1:
6 goes into 8 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 6 from 8 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 6

Advancing to step 2:
If we divide 25 by 6, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 6

Step 3:
When dividing 11 by 6, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we subtract 6 from 11, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 6

Let's proceed to step 4:
52 divided by 6 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1418.0
Subtract 48 from 52 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 6

Going ahead to step 5:
6 can be fit into 45 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 14187.0
If we take 42 away from 45, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 6

Moving on to step 6:
When dividing 33 by 6, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 141875.0
If we subtract 30 from 33, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
The number 6 fits into 30 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 141875.5
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:
0 divided by 6 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 141875.5
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.

Step 9:
6 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 141875.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 141875.5, with a leftover of 0.0.
