We look at the division of 72459603 by 853 
Our goal is to divide 72459603 by 853.

Advancing to step 1:
When dividing 7 by 853, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 853

Let's proceed to step 2:
If we divide 72 by 853, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (4) from the dividend after 72, then repeat: 724 / 853

Going ahead to step 3:
When dividing 724 by 853, we get 0 with a remainder of 724.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 724 and we're left with 724.
Fetch the next digit (5) from the dividend, attach it to 724 and continue: 7245 / 853

Let's proceed to step 4:
853 can be fit into 7245 8 times, resulting in a remainder of 421.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6824 from 7245, we get 421.
Grab the next digit (9) from the dividend, add it to 421, then carry on: 4219 / 853

On to step 5:
4219 divided by 853 is 4 with a remainder of 807.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we take 3412 away from 4219, we end up with 807.
Fetch the next digit (6) from the dividend, attach it to 807 and continue: 8076 / 853

On to step 6:
853 can be fit into 8076 9 times, resulting in a remainder of 399.
Use 9 as the next digit of our solution. 
Result so far: 849.0
Subtracting 7677 from 8076 leaves us with 399.
Grab the next digit (0) from the dividend, add it to 399, then carry on: 3990 / 853

Advancing to step 7:
853 goes into 3990 4 times with a remainder of 578.
Write down 4 as next digit of the result. 
Result so far: 8494.0
The remainder is 578 after subtracting 3412 from 3990.
Grab the next digit (3) from the dividend, add it to 578, then carry on: 5783 / 853

On to step 8:
If we divide 5783 by 853, we get 6 and a remainder of 665.
Put 6 as the next digit of the answer. 
Result so far: 84946.0
If we take 5118 away from 5783, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Moving on to step 9:
If we divide 6650 by 853, we get 7 and a remainder of 679.
Write down 7 as next digit of the result. 
Result so far: 84946.7
If we subtract 5971 from 6650, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 10:
853 goes into 6790 7 times with a remainder of 819.
Write down 7 as next digit of the result. 
Result so far: 84946.77
If we subtract 5971 from 6790, we get 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Our division results in 84946.77 with a remaining 0.819.
