We look at the division of 80749791 by 451 
We want to figure out the number of times 80749791 can be divided by 451.

Going ahead to step 1:
If we divide 8 by 451, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 451

Going ahead to step 2:
451 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (7) of the dividend behind the 80 and repeat the process: 807 / 451

Moving on to step 3:
451 goes into 807 1 times with a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 451 away from 807, we end up with 356.
Take the next digit (4) from the dividend and append it to 356, then repeat: 3564 / 451

Going ahead to step 4:
3564 divided by 451 is 7 with a remainder of 407.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 3157 from 3564, we get 407.
Fetch the next digit (9) from the dividend, attach it to 407 and continue: 4079 / 451

Moving on to step 5:
When dividing 4079 by 451, we get 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 179.0
If we take 4059 away from 4079, we end up with 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 451

Advancing to step 6:
The number 451 fits into 207 0 times, leaving a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 1790.0
Subtract 0 from 207 to get 207.
Fetch the next digit (9) from the dividend, attach it to 207 and continue: 2079 / 451

Let's proceed to step 7:
If we divide 2079 by 451, we get 4 and a remainder of 275.
Use 4 as the next digit of our solution. 
Result so far: 17904.0
Subtract 1804 from 2079 to get 275.
Bring next digit (1) of the dividend behind the 275 and repeat the process: 2751 / 451

On to step 8:
451 goes into 2751 6 times with a remainder of 45.
Put 6 as the next digit of the answer. 
Result so far: 179046.0
If we subtract 2706 from 2751, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
451 goes into 450 0 times with a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 179046.0
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
451 goes into 4500 9 times with a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 179046.09
Subtract 4059 from 4500 to get 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 11:
When dividing 4410 by 451, we get 9 with a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 179046.099
Subtract 4059 from 4410 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

The final result is 179046.099 with a remainder of 0.0351.
