80981968 divided by 345 
Our goal is to divide 80981968 by 345.

On to step 1:
8 divided by 345 is 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.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 345

Moving on to step 2:
345 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 345

Moving on to step 3:
If we divide 809 by 345, we get 2 and a remainder of 119.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 119 after subtracting 690 from 809.
Include the next digit (8) from the dividend after 119, then repeat: 1198 / 345

On to step 4:
The number 345 fits into 1198 3 times, leaving a remainder of 163.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 1035 from 1198 leaves us with 163.
Append the next digit (1) from the dividend to 163 and continue with: 1631 / 345

On to step 5:
345 goes into 1631 4 times with a remainder of 251.
Put 4 as the next digit of the answer. 
Result so far: 234.0
Subtracting 1380 from 1631 leaves us with 251.
Grab the next digit (9) from the dividend, add it to 251, then carry on: 2519 / 345

Moving on to step 6:
If we divide 2519 by 345, we get 7 and a remainder of 104.
Write down 7 as next digit of the result. 
Result so far: 2347.0
Deduct 2415 from 2519 and we're left with 104.
Bring next digit (6) of the dividend behind the 104 and repeat the process: 1046 / 345

Advancing to step 7:
345 can be fit into 1046 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 23473.0
Subtracting 1035 from 1046 leaves us with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 345

Step 8:
345 can be fit into 118 0 times, resulting in a remainder of 118.
The next digit of our result is 0. 
Result so far: 234730.0
If we subtract 0 from 118, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 9:
345 can be fit into 1180 3 times, resulting in a remainder of 145.
The next digit of our result is 3. 
Result so far: 234730.3
Subtracting 1035 from 1180 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 10:
If we divide 1450 by 345, we get 4 and a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 234730.34
If we subtract 1380 from 1450, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
345 can be fit into 700 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 234730.342
Deduct 690 from 700 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 345, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 234730.342
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
If we divide 1000 by 345, we get 2 and a remainder of 310.
Record the quotient 2 as the next digit in the result. 
Result so far: 234730.34202
Subtracting 690 from 1000 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 14:
345 can be fit into 3100 8 times, resulting in a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 234730.342028
Subtract 2760 from 3100 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 15:
345 goes into 3400 9 times with a remainder of 295.
Put 9 as the next digit of the answer. 
Result so far: 234730.3420289
Subtracting 3105 from 3400 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 16:
When dividing 2950 by 345, we get 8 with a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 234730.34202898
Deduct 2760 from 2950 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 234730.34202898 and a remainder of 1.9e-07.
