72693619 ÷ 310 
Our goal is to divide 72693619 by 310.

Going ahead to step 1:
The number 310 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
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 / 310

Advancing to step 2:
When dividing 72 by 310, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 310

Moving on to step 3:
When dividing 726 by 310, we get 2 with a remainder of 106.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 620 from 726 and we're left with 106.
Include the next digit (9) from the dividend after 106, then repeat: 1069 / 310

On to step 4:
1069 divided by 310 is 3 with a remainder of 139.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 930 from 1069, we get 139.
Fetch the next digit (3) from the dividend, attach it to 139 and continue: 1393 / 310

On to step 5:
When dividing 1393 by 310, we get 4 with a remainder of 153.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
If we subtract 1240 from 1393, we get 153.
Append the next digit (6) from the dividend to 153 and continue with: 1536 / 310

Advancing to step 6:
The number 310 fits into 1536 4 times, leaving a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 2344.0
The remainder is 296 after subtracting 1240 from 1536.
Fetch the next digit (1) from the dividend, attach it to 296 and continue: 2961 / 310

On to step 7:
The number 310 fits into 2961 9 times, leaving a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 23449.0
Subtract 2790 from 2961 to get 171.
Append the next digit (9) from the dividend to 171 and continue with: 1719 / 310

Step 8:
When dividing 1719 by 310, we get 5 with a remainder of 169.
Use 5 as the next digit of our solution. 
Result so far: 234495.0
Subtracting 1550 from 1719 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 9:
310 goes into 1690 5 times with a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 234495.5
Deduct 1550 from 1690 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
The number 310 fits into 1400 4 times, leaving a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 234495.54
Deduct 1240 from 1400 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
When dividing 1600 by 310, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 234495.545
The remainder is 50 after subtracting 1550 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
500 divided by 310 is 1 with a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 234495.5451
Subtract 310 from 500 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 13:
310 can be fit into 1900 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 234495.54516
The remainder is 40 after subtracting 1860 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
When dividing 400 by 310, we get 1 with a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 234495.545161
If we subtract 310 from 400, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 15:
When dividing 900 by 310, we get 2 with a remainder of 280.
Use 2 as the next digit of our solution. 
Result so far: 234495.5451612
Subtracting 620 from 900 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
310 goes into 2800 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 234495.54516129
Subtracting 2790 from 2800 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 234495.54516129 and a remainder of 1e-08.
