We're dividing 71899664 by 344 
We want to divide 71899664 by 344.

Step 1:
7 divided by 344 is 0 with 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.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 344

Let's proceed to step 2:
The number 344 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 344

Moving on to step 3:
When dividing 718 by 344, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 688 from 718 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 344

Going ahead to step 4:
The number 344 fits into 309 0 times, leaving a remainder of 309.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 309 leaves us with 309.
Append the next digit (9) from the dividend to 309 and continue with: 3099 / 344

Advancing to step 5:
If we divide 3099 by 344, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we subtract 3096 from 3099, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 344

Step 6:
344 can be fit into 36 0 times, resulting in a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 2090.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 344

Advancing to step 7:
344 can be fit into 366 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 20901.0
Deduct 344 from 366 and we're left with 22.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 344

Let's proceed to step 8:
If we divide 224 by 344, we get 0 and a remainder of 224.
Put 0 as the next digit of the answer. 
Result so far: 209010.0
If we take 0 away from 224, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 9:
When dividing 2240 by 344, we get 6 with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 209010.6
If we take 2064 away from 2240, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 10:
If we divide 1760 by 344, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 209010.65
The remainder is 40 after subtracting 1720 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 344, we get 1 with a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 209010.651
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
560 divided by 344 is 1 with a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 209010.6511
If we subtract 344 from 560, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The quotient of the division is 209010.6511, and the remainder is 0.00216.
