80972693 ÷ 853 
Let's see how many times 853 fits into 80972693.

Advancing to step 1:
When dividing 8 by 853, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 853

Step 2:
853 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 853

On to step 3:
The number 853 fits into 809 0 times, leaving a remainder of 809.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 809, we get 809.
Grab the next digit (7) from the dividend, add it to 809, then carry on: 8097 / 853

Step 4:
853 goes into 8097 9 times with a remainder of 420.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 7677 from 8097 to get 420.
Grab the next digit (2) from the dividend, add it to 420, then carry on: 4202 / 853

Advancing to step 5:
If we divide 4202 by 853, we get 4 and a remainder of 790.
Use 4 as the next digit of our solution. 
Result so far: 94.0
The remainder is 790 after subtracting 3412 from 4202.
Include the next digit (6) from the dividend after 790, then repeat: 7906 / 853

Step 6:
If we divide 7906 by 853, we get 9 and a remainder of 229.
The next digit of our result is 9. 
Result so far: 949.0
Subtract 7677 from 7906 to get 229.
Append the next digit (9) from the dividend to 229 and continue with: 2299 / 853

On to step 7:
The number 853 fits into 2299 2 times, leaving a remainder of 593.
Put 2 as the next digit of the answer. 
Result so far: 9492.0
If we take 1706 away from 2299, we end up with 593.
Append the next digit (3) from the dividend to 593 and continue with: 5933 / 853

Moving on to step 8:
5933 divided by 853 is 6 with a remainder of 815.
Write down 6 as next digit of the result. 
Result so far: 94926.0
Deduct 5118 from 5933 and we're left with 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

Step 9:
853 can be fit into 8150 9 times, resulting in a remainder of 473.
Write down 9 as next digit of the result. 
Result so far: 94926.9
Subtracting 7677 from 8150 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 10:
If we divide 4730 by 853, we get 5 and a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 94926.95
Subtract 4265 from 4730 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 11:
853 can be fit into 4650 5 times, resulting in a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 94926.955
If we take 4265 away from 4650, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

The final outcome is 94926.955, with a leftover of 0.0385.
