Let's divide 80661768 by 451
We want to divide 80661768 by 451.

Let's proceed to step 1:
8 divided by 451 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 451

Going ahead to step 2:
If we divide 80 by 451, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 451

Going ahead to step 3:
If we divide 806 by 451, we get 1 and a remainder of 355.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 451 from 806 leaves us with 355.
Grab the next digit (6) from the dividend, add it to 355, then carry on: 3556 / 451

Going ahead to step 4:
3556 divided by 451 is 7 with a remainder of 399.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 3157 from 3556, we get 399.
Bring next digit (1) of the dividend behind the 399 and repeat the process: 3991 / 451

On to step 5:
451 goes into 3991 8 times with a remainder of 383.
Put 8 as the next digit of the answer. 
Result so far: 178.0
Subtract 3608 from 3991 to get 383.
Bring next digit (7) of the dividend behind the 383 and repeat the process: 3837 / 451

On to step 6:
If we divide 3837 by 451, we get 8 and a remainder of 229.
The next digit of our result is 8. 
Result so far: 1788.0
Deduct 3608 from 3837 and we're left with 229.
Bring next digit (6) of the dividend behind the 229 and repeat the process: 2296 / 451

Step 7:
When dividing 2296 by 451, we get 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 17885.0
The remainder is 41 after subtracting 2255 from 2296.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 451

Let's proceed to step 8:
The number 451 fits into 418 0 times, leaving a remainder of 418.
Put 0 as the next digit of the answer. 
Result so far: 178850.0
Deduct 0 from 418 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 9:
When dividing 4180 by 451, we get 9 with a remainder of 121.
Record the quotient 9 as the next digit in the result. 
Result so far: 178850.9
The remainder is 121 after subtracting 4059 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 10:
1210 divided by 451 is 2 with a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 178850.92
Subtract 902 from 1210 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 11:
The number 451 fits into 3080 6 times, leaving a remainder of 374.
The number 6 becomes the next digit in our result. 
Result so far: 178850.926
Subtract 2706 from 3080 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 12:
3740 divided by 451 is 8 with a remainder of 132.
The next digit of our result is 8. 
Result so far: 178850.9268
Subtracting 3608 from 3740 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 13:
If we divide 1320 by 451, we get 2 and a remainder of 418.
The next digit of our result is 2. 
Result so far: 178850.92682
Subtracting 902 from 1320 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 14:
451 can be fit into 4180 9 times, resulting in a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 178850.926829
Subtracting 4059 from 4180 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 15:
1210 divided by 451 is 2 with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 178850.9268292
Subtract 902 from 1210 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 16:
When dividing 3080 by 451, we get 6 with a remainder of 374.
Use 6 as the next digit of our solution. 
Result so far: 178850.92682926
Deduct 2706 from 3080 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The final outcome is 178850.92682926, with a leftover of 3.74e-07.
