Let's divide 81352297 by 802
We want to figure out the number of times 81352297 can be divided by 802.

Let's proceed to step 1:
The number 802 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 802

Going ahead to step 2:
If we divide 81 by 802, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 802

Step 3:
When dividing 813 by 802, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 802 from 813, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 802

On to step 4:
802 goes into 115 0 times with a remainder of 115.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 115 after subtracting 0 from 115.
Include the next digit (2) from the dividend after 115, then repeat: 1152 / 802

Going ahead to step 5:
802 goes into 1152 1 times with a remainder of 350.
Put 1 as the next digit of the answer. 
Result so far: 101.0
The remainder is 350 after subtracting 802 from 1152.
Grab the next digit (2) from the dividend, add it to 350, then carry on: 3502 / 802

Moving on to step 6:
802 can be fit into 3502 4 times, resulting in a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 1014.0
Subtract 3208 from 3502 to get 294.
Grab the next digit (9) from the dividend, add it to 294, then carry on: 2949 / 802

Step 7:
802 can be fit into 2949 3 times, resulting in a remainder of 543.
The number 3 becomes the next digit in our result. 
Result so far: 10143.0
Subtracting 2406 from 2949 leaves us with 543.
Bring next digit (7) of the dividend behind the 543 and repeat the process: 5437 / 802

Going ahead to step 8:
The number 802 fits into 5437 6 times, leaving a remainder of 625.
The number 6 becomes the next digit in our result. 
Result so far: 101436.0
If we take 4812 away from 5437, we end up with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 9:
The number 802 fits into 6250 7 times, leaving a remainder of 636.
The next digit of our result is 7. 
Result so far: 101436.7
Subtract 5614 from 6250 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 10:
802 can be fit into 6360 7 times, resulting in a remainder of 746.
Use 7 as the next digit of our solution. 
Result so far: 101436.77
Subtracting 5614 from 6360 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

The final outcome is 101436.77, with a leftover of 0.746.
