We're dividing 72428919 by 731 
We want to divide 72428919 by 731.

Let's proceed to step 1:
The number 731 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 731

Let's proceed to step 2:
72 divided by 731 is 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 731

On to step 3:
If we divide 724 by 731, we get 0 and a remainder of 724.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 724, we end up with 724.
Take the next digit (2) from the dividend and append it to 724, then repeat: 7242 / 731

Advancing to step 4:
If we divide 7242 by 731, we get 9 and a remainder of 663.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 663 after subtracting 6579 from 7242.
Append the next digit (8) from the dividend to 663 and continue with: 6638 / 731

Advancing to step 5:
731 can be fit into 6638 9 times, resulting in a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtracting 6579 from 6638 leaves us with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 731

Let's proceed to step 6:
The number 731 fits into 599 0 times, leaving a remainder of 599.
Record the quotient 0 as the next digit in the result. 
Result so far: 990.0
Deduct 0 from 599 and we're left with 599.
Append the next digit (1) from the dividend to 599 and continue with: 5991 / 731

Going ahead to step 7:
The number 731 fits into 5991 8 times, leaving a remainder of 143.
Use 8 as the next digit of our solution. 
Result so far: 9908.0
If we take 5848 away from 5991, we end up with 143.
Append the next digit (9) from the dividend to 143 and continue with: 1439 / 731

Step 8:
When dividing 1439 by 731, we get 1 with a remainder of 708.
Put 1 as the next digit of the answer. 
Result so far: 99081.0
The remainder is 708 after subtracting 731 from 1439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 9:
The number 731 fits into 7080 9 times, leaving a remainder of 501.
The number 9 becomes the next digit in our result. 
Result so far: 99081.9
Subtracting 6579 from 7080 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Going ahead to step 10:
5010 divided by 731 is 6 with a remainder of 624.
Use 6 as the next digit of our solution. 
Result so far: 99081.96
Deduct 4386 from 5010 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 11:
731 goes into 6240 8 times with a remainder of 392.
Record the quotient 8 as the next digit in the result. 
Result so far: 99081.968
If we subtract 5848 from 6240, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 12:
731 goes into 3920 5 times with a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 99081.9685
If we subtract 3655 from 3920, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 13:
731 can be fit into 2650 3 times, resulting in a remainder of 457.
The next digit of our result is 3. 
Result so far: 99081.96853
If we subtract 2193 from 2650, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 14:
When dividing 4570 by 731, we get 6 with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 99081.968536
The remainder is 184 after subtracting 4386 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
731 can be fit into 1840 2 times, resulting in a remainder of 378.
Use 2 as the next digit of our solution. 
Result so far: 99081.9685362
Subtracting 1462 from 1840 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 16:
The number 731 fits into 3780 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 99081.96853625
If we subtract 3655 from 3780, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 99081.96853625 and a remainder of 1.25e-07.
