Let's divide 81676903 by 451
We want to figure out the number of times 81676903 can be divided by 451.

Advancing to step 1:
451 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 451

Advancing to step 2:
451 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 451

Moving on to step 3:
451 can be fit into 816 1 times, resulting in a remainder of 365.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 365 after subtracting 451 from 816.
Fetch the next digit (7) from the dividend, attach it to 365 and continue: 3657 / 451

Step 4:
When dividing 3657 by 451, we get 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 3608 from 3657 leaves us with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 451

Step 5:
496 divided by 451 is 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
Subtract 451 from 496 to get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 451

Advancing to step 6:
The number 451 fits into 459 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1811.0
Subtracting 451 from 459 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 451

On to step 7:
451 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 18110.0
If we subtract 0 from 80, we get 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 451

Advancing to step 8:
The number 451 fits into 803 1 times, leaving a remainder of 352.
The number 1 becomes the next digit in our result. 
Result so far: 181101.0
If we subtract 451 from 803, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 9:
3520 divided by 451 is 7 with a remainder of 363.
Put 7 as the next digit of the answer. 
Result so far: 181101.7
If we subtract 3157 from 3520, we get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 10:
The number 451 fits into 3630 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 181101.78
If we take 3608 away from 3630, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
220 divided by 451 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 181101.78
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
2200 divided by 451 is 4 with a remainder of 396.
Write down 4 as next digit of the result. 
Result so far: 181101.7804
If we subtract 1804 from 2200, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 13:
If we divide 3960 by 451, we get 8 and a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 181101.78048
Subtracting 3608 from 3960 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 14:
3520 divided by 451 is 7 with a remainder of 363.
The number 7 becomes the next digit in our result. 
Result so far: 181101.780487
Deduct 3157 from 3520 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 15:
3630 divided by 451 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 181101.7804878
Subtracting 3608 from 3630 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 16:
The number 451 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 181101.7804878
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Our division results in 181101.7804878 with a remaining 2.2e-07.
