357197 ÷ 81 
We want to figure out the number of times 357197 can be divided by 81.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 81

Step 2:
35 divided by 81 is 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 81

On to step 3:
81 goes into 357 4 times with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 324 from 357 leaves us with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 81

On to step 4:
81 goes into 331 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 324 from 331 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 81

Going ahead to step 5:
81 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 440.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 81

Let's proceed to step 6:
If we divide 797 by 81, we get 9 and a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 4409.0
If we subtract 729 from 797, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
When dividing 680 by 81, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 4409.8
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
81 goes into 320 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 4409.83
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
The number 81 fits into 770 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 4409.839
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
81 goes into 410 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4409.8395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
81 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 4409.8395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
81 can be fit into 500 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4409.839506
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
If we divide 140 by 81, we get 1 and a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 4409.8395061
Subtracting 81 from 140 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
81 goes into 590 7 times with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 4409.83950617
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 4409.83950617, with a leftover of 2.3e-08.
