72371143 ÷ 453 
Our goal is to divide 72371143 by 453.

Going ahead to step 1:
7 divided by 453 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 453

Step 2:
When dividing 72 by 453, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Fetch the next digit (3) from the dividend, attach it to 72 and continue: 723 / 453

Moving on to step 3:
The number 453 fits into 723 1 times, leaving a remainder of 270.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 270 after subtracting 453 from 723.
Bring next digit (7) of the dividend behind the 270 and repeat the process: 2707 / 453

Let's proceed to step 4:
The number 453 fits into 2707 5 times, leaving a remainder of 442.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2265 from 2707 to get 442.
Take the next digit (1) from the dividend and append it to 442, then repeat: 4421 / 453

Let's proceed to step 5:
If we divide 4421 by 453, we get 9 and a remainder of 344.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we take 4077 away from 4421, we end up with 344.
Fetch the next digit (1) from the dividend, attach it to 344 and continue: 3441 / 453

Moving on to step 6:
If we divide 3441 by 453, we get 7 and a remainder of 270.
Record the quotient 7 as the next digit in the result. 
Result so far: 1597.0
Deduct 3171 from 3441 and we're left with 270.
Include the next digit (4) from the dividend after 270, then repeat: 2704 / 453

Going ahead to step 7:
When dividing 2704 by 453, we get 5 with a remainder of 439.
Use 5 as the next digit of our solution. 
Result so far: 15975.0
If we take 2265 away from 2704, we end up with 439.
Include the next digit (3) from the dividend after 439, then repeat: 4393 / 453

Step 8:
The number 453 fits into 4393 9 times, leaving a remainder of 316.
Record the quotient 9 as the next digit in the result. 
Result so far: 159759.0
Deduct 4077 from 4393 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 9:
The number 453 fits into 3160 6 times, leaving a remainder of 442.
Write down 6 as next digit of the result. 
Result so far: 159759.6
The remainder is 442 after subtracting 2718 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
4420 divided by 453 is 9 with a remainder of 343.
The next digit of our result is 9. 
Result so far: 159759.69
Subtract 4077 from 4420 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 11:
If we divide 3430 by 453, we get 7 and a remainder of 259.
The next digit of our result is 7. 
Result so far: 159759.697
Subtracting 3171 from 3430 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 12:
When dividing 2590 by 453, we get 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 159759.6975
Subtracting 2265 from 2590 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 13:
When dividing 3250 by 453, we get 7 with a remainder of 79.
The next digit of our result is 7. 
Result so far: 159759.69757
The remainder is 79 after subtracting 3171 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 14:
453 can be fit into 790 1 times, resulting in a remainder of 337.
Put 1 as the next digit of the answer. 
Result so far: 159759.697571
The remainder is 337 after subtracting 453 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 15:
453 can be fit into 3370 7 times, resulting in a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 159759.6975717
Deduct 3171 from 3370 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 16:
453 goes into 1990 4 times with a remainder of 178.
The next digit of our result is 4. 
Result so far: 159759.69757174
The remainder is 178 after subtracting 1812 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 159759.69757174 and a remainder of 1.78e-07.
