Let's divide 81301991 by 354
We want to figure out the number of times 81301991 can be divided by 354.

Advancing to step 1:
354 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 354

On to step 2:
354 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 354

Moving on to step 3:
354 can be fit into 813 2 times, resulting in a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 708 from 813 to get 105.
Bring next digit (0) of the dividend behind the 105 and repeat the process: 1050 / 354

Let's proceed to step 4:
1050 divided by 354 is 2 with a remainder of 342.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 342 after subtracting 708 from 1050.
Bring next digit (1) of the dividend behind the 342 and repeat the process: 3421 / 354

Going ahead to step 5:
When dividing 3421 by 354, we get 9 with a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
If we take 3186 away from 3421, we end up with 235.
Fetch the next digit (9) from the dividend, attach it to 235 and continue: 2359 / 354

Let's proceed to step 6:
The number 354 fits into 2359 6 times, leaving a remainder of 235.
Write down 6 as next digit of the result. 
Result so far: 2296.0
If we take 2124 away from 2359, we end up with 235.
Include the next digit (9) from the dividend after 235, then repeat: 2359 / 354

Moving on to step 7:
The number 354 fits into 2359 6 times, leaving a remainder of 235.
Record the quotient 6 as the next digit in the result. 
Result so far: 22966.0
Deduct 2124 from 2359 and we're left with 235.
Grab the next digit (1) from the dividend, add it to 235, then carry on: 2351 / 354

Going ahead to step 8:
354 can be fit into 2351 6 times, resulting in a remainder of 227.
The next digit of our result is 6. 
Result so far: 229666.0
Subtracting 2124 from 2351 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 9:
When dividing 2270 by 354, we get 6 with a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 229666.6
The remainder is 146 after subtracting 2124 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 10:
1460 divided by 354 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 229666.64
Deduct 1416 from 1460 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
354 goes into 440 1 times with a remainder of 86.
Use 1 as the next digit of our solution. 
Result so far: 229666.641
Subtracting 354 from 440 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 12:
354 can be fit into 860 2 times, resulting in a remainder of 152.
The next digit of our result is 2. 
Result so far: 229666.6412
The remainder is 152 after subtracting 708 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 13:
1520 divided by 354 is 4 with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 229666.64124
Subtracting 1416 from 1520 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 14:
The number 354 fits into 1040 2 times, leaving a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 229666.641242
If we subtract 708 from 1040, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 15:
If we divide 3320 by 354, we get 9 and a remainder of 134.
The number 9 becomes the next digit in our result. 
Result so far: 229666.6412429
Subtract 3186 from 3320 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 16:
354 goes into 1340 3 times with a remainder of 278.
The number 3 becomes the next digit in our result. 
Result so far: 229666.64124293
The remainder is 278 after subtracting 1062 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The quotient of the division is 229666.64124293, and the remainder is 2.78e-07.
