We look at the division of 81035109 by 351 
We're looking to find how many times 351 goes into 81035109.

Moving on to step 1:
351 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 351

On to step 2:
If we divide 81 by 351, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 351

Moving on to step 3:
351 goes into 810 2 times with a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 702 from 810 leaves us with 108.
Include the next digit (3) from the dividend after 108, then repeat: 1083 / 351

On to step 4:
If we divide 1083 by 351, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 1053 from 1083 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 351

Let's proceed to step 5:
When dividing 305 by 351, we get 0 with a remainder of 305.
Use 0 as the next digit of our solution. 
Result so far: 230.0
Subtracting 0 from 305 leaves us with 305.
Append the next digit (1) from the dividend to 305 and continue with: 3051 / 351

Moving on to step 6:
If we divide 3051 by 351, we get 8 and a remainder of 243.
Write down 8 as next digit of the result. 
Result so far: 2308.0
If we subtract 2808 from 3051, we get 243.
Grab the next digit (0) from the dividend, add it to 243, then carry on: 2430 / 351

On to step 7:
2430 divided by 351 is 6 with a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 23086.0
Subtracting 2106 from 2430 leaves us with 324.
Take the next digit (9) from the dividend and append it to 324, then repeat: 3249 / 351

On to step 8:
If we divide 3249 by 351, we get 9 and a remainder of 90.
The next digit of our result is 9. 
Result so far: 230869.0
If we take 3159 away from 3249, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 9:
If we divide 900 by 351, we get 2 and a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 230869.2
If we take 702 away from 900, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
1980 divided by 351 is 5 with a remainder of 225.
The next digit of our result is 5. 
Result so far: 230869.25
If we take 1755 away from 1980, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 11:
The number 351 fits into 2250 6 times, leaving a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 230869.256
Deduct 2106 from 2250 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
351 can be fit into 1440 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 230869.2564
Deduct 1404 from 1440 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.

Advancing to step 13:
The number 351 fits into 360 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 230869.25641
Subtract 351 from 360 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
90 divided by 351 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 230869.25641
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
351 goes into 900 2 times with a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 230869.2564102
Subtracting 702 from 900 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 16:
1980 divided by 351 is 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 230869.25641025
If we subtract 1755 from 1980, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

In conclusion, the division gives 230869.25641025 with a balance of 2.25e-07.
