We're dividing 81305358 by 193 
We want to figure out the number of times 81305358 can be divided by 193.

Advancing to step 1:
If we divide 8 by 193, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 193

On to step 2:
193 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 193

Moving on to step 3:
The number 193 fits into 813 4 times, leaving a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 772 from 813 to get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 193

Step 4:
410 divided by 193 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 386 from 410 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 193

Moving on to step 5:
If we divide 245 by 193, we get 1 and a remainder of 52.
The next digit of our result is 1. 
Result so far: 421.0
Subtracting 193 from 245 leaves us with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 193

Going ahead to step 6:
523 divided by 193 is 2 with a remainder of 137.
Put 2 as the next digit of the answer. 
Result so far: 4212.0
Deduct 386 from 523 and we're left with 137.
Take the next digit (5) from the dividend and append it to 137, then repeat: 1375 / 193

Moving on to step 7:
193 goes into 1375 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 42127.0
If we subtract 1351 from 1375, we get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 193

Step 8:
248 divided by 193 is 1 with a remainder of 55.
The next digit of our result is 1. 
Result so far: 421271.0
Deduct 193 from 248 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 9:
193 goes into 550 2 times with a remainder of 164.
Write down 2 as next digit of the result. 
Result so far: 421271.2
If we take 386 away from 550, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
1640 divided by 193 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 421271.28
The remainder is 96 after subtracting 1544 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 11:
193 goes into 960 4 times with a remainder of 188.
The next digit of our result is 4. 
Result so far: 421271.284
If we take 772 away from 960, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 12:
When dividing 1880 by 193, we get 9 with a remainder of 143.
The next digit of our result is 9. 
Result so far: 421271.2849
Subtract 1737 from 1880 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 13:
The number 193 fits into 1430 7 times, leaving a remainder of 79.
Use 7 as the next digit of our solution. 
Result so far: 421271.28497
If we subtract 1351 from 1430, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 14:
790 divided by 193 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 421271.284974
The remainder is 18 after subtracting 772 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 15:
When dividing 180 by 193, we get 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 421271.284974
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
When dividing 1800 by 193, we get 9 with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 421271.28497409
Subtracting 1737 from 1800 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 421271.28497409, and the remainder is 6.3e-08.
