81026199 ÷ 353 
Our goal is to divide 81026199 by 353.

Let's proceed to step 1:
If we divide 8 by 353, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 353

On to step 2:
353 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 353

Moving on to step 3:
353 goes into 810 2 times with a remainder of 104.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 706 from 810, we get 104.
Include the next digit (2) from the dividend after 104, then repeat: 1042 / 353

Step 4:
If we divide 1042 by 353, we get 2 and a remainder of 336.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 336 after subtracting 706 from 1042.
Grab the next digit (6) from the dividend, add it to 336, then carry on: 3366 / 353

Let's proceed to step 5:
353 goes into 3366 9 times with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 229.0
If we subtract 3177 from 3366, we get 189.
Grab the next digit (1) from the dividend, add it to 189, then carry on: 1891 / 353

Step 6:
353 can be fit into 1891 5 times, resulting in a remainder of 126.
Put 5 as the next digit of the answer. 
Result so far: 2295.0
Deduct 1765 from 1891 and we're left with 126.
Grab the next digit (9) from the dividend, add it to 126, then carry on: 1269 / 353

Moving on to step 7:
353 goes into 1269 3 times with a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 22953.0
Deduct 1059 from 1269 and we're left with 210.
Bring next digit (9) of the dividend behind the 210 and repeat the process: 2109 / 353

Going ahead to step 8:
When dividing 2109 by 353, we get 5 with a remainder of 344.
Write down 5 as next digit of the result. 
Result so far: 229535.0
Subtracting 1765 from 2109 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 9:
353 can be fit into 3440 9 times, resulting in a remainder of 263.
Use 9 as the next digit of our solution. 
Result so far: 229535.9
If we take 3177 away from 3440, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 10:
353 goes into 2630 7 times with a remainder of 159.
Use 7 as the next digit of our solution. 
Result so far: 229535.97
If we subtract 2471 from 2630, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 11:
353 goes into 1590 4 times with a remainder of 178.
Record the quotient 4 as the next digit in the result. 
Result so far: 229535.974
The remainder is 178 after subtracting 1412 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 12:
When dividing 1780 by 353, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 229535.9745
Subtracting 1765 from 1780 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
The number 353 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 229535.9745
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 14:
353 goes into 1500 4 times with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 229535.974504
Deduct 1412 from 1500 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
When dividing 880 by 353, we get 2 with a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 229535.9745042
If we subtract 706 from 880, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 16:
353 can be fit into 1740 4 times, resulting in a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 229535.97450424
Deduct 1412 from 1740 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 229535.97450424, with a leftover of 3.28e-07.
