81675398 ÷ 342 
We want to figure out the number of times 81675398 can be divided by 342.

On to step 1:
The number 342 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 342

On to step 2:
When dividing 81 by 342, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 342

Going ahead to step 3:
816 divided by 342 is 2 with a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 684 away from 816, we end up with 132.
Fetch the next digit (7) from the dividend, attach it to 132 and continue: 1327 / 342

Going ahead to step 4:
When dividing 1327 by 342, we get 3 with a remainder of 301.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 301 after subtracting 1026 from 1327.
Take the next digit (5) from the dividend and append it to 301, then repeat: 3015 / 342

Going ahead to step 5:
If we divide 3015 by 342, we get 8 and a remainder of 279.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Deduct 2736 from 3015 and we're left with 279.
Append the next digit (3) from the dividend to 279 and continue with: 2793 / 342

Advancing to step 6:
2793 divided by 342 is 8 with a remainder of 57.
The next digit of our result is 8. 
Result so far: 2388.0
Subtract 2736 from 2793 to get 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 342

Moving on to step 7:
579 divided by 342 is 1 with a remainder of 237.
The next digit of our result is 1. 
Result so far: 23881.0
The remainder is 237 after subtracting 342 from 579.
Grab the next digit (8) from the dividend, add it to 237, then carry on: 2378 / 342

Advancing to step 8:
342 goes into 2378 6 times with a remainder of 326.
Record the quotient 6 as the next digit in the result. 
Result so far: 238816.0
If we take 2052 away from 2378, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 9:
342 can be fit into 3260 9 times, resulting in a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 238816.9
Subtract 3078 from 3260 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 10:
342 goes into 1820 5 times with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 238816.95
The remainder is 110 after subtracting 1710 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 11:
When dividing 1100 by 342, we get 3 with a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 238816.953
Subtract 1026 from 1100 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
342 can be fit into 740 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 238816.9532
If we take 684 away from 740, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
When dividing 560 by 342, we get 1 with a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 238816.95321
The remainder is 218 after subtracting 342 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 14:
The number 342 fits into 2180 6 times, leaving a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 238816.953216
If we subtract 2052 from 2180, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 15:
1280 divided by 342 is 3 with a remainder of 254.
The next digit of our result is 3. 
Result so far: 238816.9532163
Subtracting 1026 from 1280 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 16:
If we divide 2540 by 342, we get 7 and a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 238816.95321637
Subtract 2394 from 2540 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 238816.95321637 with a remainder of 1.46e-07.
