We're dividing 80378479 by 451 
We want to figure out the number of times 80378479 can be divided by 451.

Let's proceed to step 1:
When dividing 8 by 451, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 451

Let's proceed to step 2:
The number 451 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 451

Step 3:
If we divide 803 by 451, we get 1 and a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 451 away from 803, we end up with 352.
Grab the next digit (7) from the dividend, add it to 352, then carry on: 3527 / 451

Advancing to step 4:
If we divide 3527 by 451, we get 7 and a remainder of 370.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 3157 from 3527 to get 370.
Include the next digit (8) from the dividend after 370, then repeat: 3708 / 451

Moving on to step 5:
451 can be fit into 3708 8 times, resulting in a remainder of 100.
The next digit of our result is 8. 
Result so far: 178.0
Deduct 3608 from 3708 and we're left with 100.
Grab the next digit (4) from the dividend, add it to 100, then carry on: 1004 / 451

On to step 6:
451 can be fit into 1004 2 times, resulting in a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 1782.0
Subtract 902 from 1004 to get 102.
Include the next digit (7) from the dividend after 102, then repeat: 1027 / 451

Let's proceed to step 7:
If we divide 1027 by 451, we get 2 and a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 17822.0
If we subtract 902 from 1027, we get 125.
Fetch the next digit (9) from the dividend, attach it to 125 and continue: 1259 / 451

Going ahead to step 8:
If we divide 1259 by 451, we get 2 and a remainder of 357.
Use 2 as the next digit of our solution. 
Result so far: 178222.0
Deduct 902 from 1259 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 9:
451 can be fit into 3570 7 times, resulting in a remainder of 413.
Put 7 as the next digit of the answer. 
Result so far: 178222.7
The remainder is 413 after subtracting 3157 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 10:
451 goes into 4130 9 times with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 178222.79
Subtracting 4059 from 4130 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 11:
The number 451 fits into 710 1 times, leaving a remainder of 259.
The number 1 becomes the next digit in our result. 
Result so far: 178222.791
If we subtract 451 from 710, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 12:
2590 divided by 451 is 5 with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 178222.7915
If we take 2255 away from 2590, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 13:
The number 451 fits into 3350 7 times, leaving a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 178222.79157
Subtract 3157 from 3350 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 14:
The number 451 fits into 1930 4 times, leaving a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 178222.791574
Subtracting 1804 from 1930 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 15:
451 can be fit into 1260 2 times, resulting in a remainder of 358.
Record the quotient 2 as the next digit in the result. 
Result so far: 178222.7915742
Subtract 902 from 1260 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 16:
451 can be fit into 3580 7 times, resulting in a remainder of 423.
The number 7 becomes the next digit in our result. 
Result so far: 178222.79157427
Deduct 3157 from 3580 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

The quotient of the division is 178222.79157427, and the remainder is 4.23e-07.
