81790468 ÷ 355 
We want to divide 81790468 by 355.

Advancing to step 1:
The number 355 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 355

On to step 2:
355 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
Subtracting 0 from 81 leaves us with 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 355

On to step 3:
817 divided by 355 is 2 with a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 710 away from 817, we end up with 107.
Grab the next digit (9) from the dividend, add it to 107, then carry on: 1079 / 355

Let's proceed to step 4:
The number 355 fits into 1079 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 1065 from 1079 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 355

Advancing to step 5:
355 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 230.0
If we take 0 away from 140, we end up with 140.
Bring next digit (4) of the dividend behind the 140 and repeat the process: 1404 / 355

Moving on to step 6:
If we divide 1404 by 355, we get 3 and a remainder of 339.
Write down 3 as next digit of the result. 
Result so far: 2303.0
Subtracting 1065 from 1404 leaves us with 339.
Take the next digit (6) from the dividend and append it to 339, then repeat: 3396 / 355

Moving on to step 7:
When dividing 3396 by 355, we get 9 with a remainder of 201.
The number 9 becomes the next digit in our result. 
Result so far: 23039.0
Subtracting 3195 from 3396 leaves us with 201.
Append the next digit (8) from the dividend to 201 and continue with: 2018 / 355

Let's proceed to step 8:
The number 355 fits into 2018 5 times, leaving a remainder of 243.
Put 5 as the next digit of the answer. 
Result so far: 230395.0
Deduct 1775 from 2018 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Moving on to step 9:
355 can be fit into 2430 6 times, resulting in a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 230395.6
If we subtract 2130 from 2430, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
3000 divided by 355 is 8 with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 230395.68
Subtract 2840 from 3000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
1600 divided by 355 is 4 with a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 230395.684
If we subtract 1420 from 1600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 12:
If we divide 1800 by 355, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 230395.6845
If we take 1775 away from 1800, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
355 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 230395.6845
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
355 goes into 2500 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 230395.684507
Subtracting 2485 from 2500 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.

On to step 15:
355 can be fit into 150 0 times, resulting in a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 230395.684507
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 16:
When dividing 1500 by 355, we get 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 230395.68450704
The remainder is 80 after subtracting 1420 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 230395.68450704 with a balance of 8e-08.
