We look at the division of 81531957 by 353 
We're looking to find how many times 353 goes into 81531957.

Advancing to step 1:
When dividing 8 by 353, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 353

Step 2:
The number 353 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 353

Advancing to step 3:
353 can be fit into 815 2 times, resulting in a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 706 from 815 to get 109.
Fetch the next digit (3) from the dividend, attach it to 109 and continue: 1093 / 353

Advancing to step 4:
1093 divided by 353 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 34 after subtracting 1059 from 1093.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 353

Advancing to step 5:
353 can be fit into 341 0 times, resulting in a remainder of 341.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Subtract 0 from 341 to get 341.
Append the next digit (9) from the dividend to 341 and continue with: 3419 / 353

Let's proceed to step 6:
If we divide 3419 by 353, we get 9 and a remainder of 242.
The number 9 becomes the next digit in our result. 
Result so far: 2309.0
The remainder is 242 after subtracting 3177 from 3419.
Include the next digit (5) from the dividend after 242, then repeat: 2425 / 353

On to step 7:
2425 divided by 353 is 6 with a remainder of 307.
The number 6 becomes the next digit in our result. 
Result so far: 23096.0
If we subtract 2118 from 2425, we get 307.
Grab the next digit (7) from the dividend, add it to 307, then carry on: 3077 / 353

Advancing to step 8:
353 can be fit into 3077 8 times, resulting in a remainder of 253.
The next digit of our result is 8. 
Result so far: 230968.0
Subtracting 2824 from 3077 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 9:
353 goes into 2530 7 times with a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 230968.7
The remainder is 59 after subtracting 2471 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 10:
353 goes into 590 1 times with a remainder of 237.
The number 1 becomes the next digit in our result. 
Result so far: 230968.71
The remainder is 237 after subtracting 353 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 11:
If we divide 2370 by 353, we get 6 and a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 230968.716
If we subtract 2118 from 2370, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
The number 353 fits into 2520 7 times, leaving a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 230968.7167
Subtracting 2471 from 2520 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.

Advancing to step 13:
490 divided by 353 is 1 with a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 230968.71671
Deduct 353 from 490 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 14:
If we divide 1370 by 353, we get 3 and a remainder of 311.
Use 3 as the next digit of our solution. 
Result so far: 230968.716713
The remainder is 311 after subtracting 1059 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 15:
If we divide 3110 by 353, we get 8 and a remainder of 286.
Put 8 as the next digit of the answer. 
Result so far: 230968.7167138
The remainder is 286 after subtracting 2824 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 16:
2860 divided by 353 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 230968.71671388
Deduct 2824 from 2860 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 230968.71671388, and the remainder is 3.6e-08.
