We divide 21192450 by 310
We want to divide 21192450 by 310.

On to step 1:
If we divide 2 by 310, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 310

Advancing to step 2:
If we divide 21 by 310, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 310

Going ahead to step 3:
310 can be fit into 211 0 times, resulting in a remainder of 211.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Take the next digit (9) from the dividend and append it to 211, then repeat: 2119 / 310

Step 4:
310 can be fit into 2119 6 times, resulting in a remainder of 259.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 1860 from 2119 leaves us with 259.
Include the next digit (2) from the dividend after 259, then repeat: 2592 / 310

Going ahead to step 5:
The number 310 fits into 2592 8 times, leaving a remainder of 112.
The next digit of our result is 8. 
Result so far: 68.0
Subtract 2480 from 2592 to get 112.
Grab the next digit (4) from the dividend, add it to 112, then carry on: 1124 / 310

On to step 6:
If we divide 1124 by 310, we get 3 and a remainder of 194.
Put 3 as the next digit of the answer. 
Result so far: 683.0
If we take 930 away from 1124, we end up with 194.
Take the next digit (5) from the dividend and append it to 194, then repeat: 1945 / 310

On to step 7:
The number 310 fits into 1945 6 times, leaving a remainder of 85.
The number 6 becomes the next digit in our result. 
Result so far: 6836.0
Deduct 1860 from 1945 and we're left with 85.
Fetch the next digit (0) from the dividend, attach it to 85 and continue: 850 / 310

Moving on to step 8:
850 divided by 310 is 2 with a remainder of 230.
Put 2 as the next digit of the answer. 
Result so far: 68362.0
If we take 620 away from 850, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 9:
310 goes into 2300 7 times with a remainder of 130.
The next digit of our result is 7. 
Result so far: 68362.7
If we take 2170 away from 2300, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
The number 310 fits into 1300 4 times, leaving a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 68362.74
The remainder is 60 after subtracting 1240 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 310 is 1 with a remainder of 290.
The next digit of our result is 1. 
Result so far: 68362.741
Deduct 310 from 600 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 12:
310 goes into 2900 9 times with a remainder of 110.
The next digit of our result is 9. 
Result so far: 68362.7419
Deduct 2790 from 2900 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 13:
310 can be fit into 1100 3 times, resulting in a remainder of 170.
The next digit of our result is 3. 
Result so far: 68362.74193
If we take 930 away from 1100, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
When dividing 1700 by 310, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 68362.741935
If we take 1550 away from 1700, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
The number 310 fits into 1500 4 times, leaving a remainder of 260.
The next digit of our result is 4. 
Result so far: 68362.7419354
If we subtract 1240 from 1500, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 16:
The number 310 fits into 2600 8 times, leaving a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 68362.74193548
If we take 2480 away from 2600, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The quotient of the division is 68362.74193548, and the remainder is 1.2e-07.
