We're dividing 357313 by 81 
We want to figure out the number of times 357313 can be divided by 81.

Let's proceed to step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 81

Advancing to step 2:
81 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 81

Let's proceed to step 3:
When dividing 357 by 81, we get 4 with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 324 from 357 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 81

Going ahead to step 4:
81 goes into 333 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 324 from 333, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 81

Going ahead to step 5:
When dividing 91 by 81, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
If we take 81 away from 91, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 81

Moving on to step 6:
103 divided by 81 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 4411.0
If we subtract 81 from 103, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 4411.2
If we subtract 162 from 220, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 4411.27
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 81, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4411.271
Subtracting 81 from 130 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
81 can be fit into 490 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 4411.2716
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
81 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4411.2716
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 81, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 4411.271604
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
81 can be fit into 760 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 4411.2716049
Deduct 729 from 760 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
When dividing 310 by 81, we get 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 4411.27160493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 4411.27160493, and the remainder is 6.7e-08.
