80642899 ÷ 347 
Let's see how many times 347 fits into 80642899.

On to step 1:
If we divide 8 by 347, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 347

Going ahead to step 2:
80 divided by 347 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 347

On to step 3:
If we divide 806 by 347, we get 2 and a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 694 from 806, we get 112.
Grab the next digit (4) from the dividend, add it to 112, then carry on: 1124 / 347

Going ahead to step 4:
1124 divided by 347 is 3 with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 1041 from 1124, we get 83.
Fetch the next digit (2) from the dividend, attach it to 83 and continue: 832 / 347

On to step 5:
If we divide 832 by 347, we get 2 and a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 232.0
Deduct 694 from 832 and we're left with 138.
Append the next digit (8) from the dividend to 138 and continue with: 1388 / 347

Let's proceed to step 6:
347 can be fit into 1388 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2324.0
Subtracting 1388 from 1388 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 347

Going ahead to step 7:
347 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 23240.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 347

Advancing to step 8:
When dividing 99 by 347, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 232400.0
If we subtract 0 from 99, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 9:
990 divided by 347 is 2 with a remainder of 296.
The next digit of our result is 2. 
Result so far: 232400.2
Subtract 694 from 990 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 10:
If we divide 2960 by 347, we get 8 and a remainder of 184.
The next digit of our result is 8. 
Result so far: 232400.28
Subtracting 2776 from 2960 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
The number 347 fits into 1840 5 times, leaving a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 232400.285
If we subtract 1735 from 1840, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 12:
1050 divided by 347 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 232400.2853
If we subtract 1041 from 1050, we 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 13:
The number 347 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 232400.2853
Subtracting 0 from 90 leaves us 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.

Going ahead to step 14:
347 goes into 900 2 times with a remainder of 206.
The next digit of our result is 2. 
Result so far: 232400.285302
The remainder is 206 after subtracting 694 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 15:
When dividing 2060 by 347, we get 5 with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 232400.2853025
If we subtract 1735 from 2060, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 16:
347 goes into 3250 9 times with a remainder of 127.
Use 9 as the next digit of our solution. 
Result so far: 232400.28530259
Subtracting 3123 from 3250 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final outcome is 232400.28530259, with a leftover of 1.27e-07.
