81437811 divided by 342 
The aim is to understand the frequency of 342 in 81437811.

Moving on to step 1:
342 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 342

Going ahead to step 2:
342 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 342

On to step 3:
When dividing 814 by 342, we get 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 684 from 814 and we're left with 130.
Append the next digit (3) from the dividend to 130 and continue with: 1303 / 342

Step 4:
If we divide 1303 by 342, we get 3 and a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 1026 from 1303, we get 277.
Append the next digit (7) from the dividend to 277 and continue with: 2777 / 342

Let's proceed to step 5:
If we divide 2777 by 342, we get 8 and a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
If we take 2736 away from 2777, we end up with 41.
Fetch the next digit (8) from the dividend, attach it to 41 and continue: 418 / 342

Let's proceed to step 6:
The number 342 fits into 418 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 2381.0
Deduct 342 from 418 and we're left with 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 342

Moving on to step 7:
The number 342 fits into 761 2 times, leaving a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 23812.0
If we subtract 684 from 761, we get 77.
Append the next digit (1) from the dividend to 77 and continue with: 771 / 342

Advancing to step 8:
When dividing 771 by 342, we get 2 with a remainder of 87.
Put 2 as the next digit of the answer. 
Result so far: 238122.0
The remainder is 87 after subtracting 684 from 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
342 goes into 870 2 times with a remainder of 186.
Record the quotient 2 as the next digit in the result. 
Result so far: 238122.2
Subtracting 684 from 870 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 10:
342 goes into 1860 5 times with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 238122.25
If we subtract 1710 from 1860, 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 11:
If we divide 1500 by 342, we get 4 and a remainder of 132.
Write down 4 as next digit of the result. 
Result so far: 238122.254
The remainder is 132 after subtracting 1368 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 12:
When dividing 1320 by 342, we get 3 with a remainder of 294.
Write down 3 as next digit of the result. 
Result so far: 238122.2543
Deduct 1026 from 1320 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 13:
When dividing 2940 by 342, we get 8 with a remainder of 204.
Use 8 as the next digit of our solution. 
Result so far: 238122.25438
Subtract 2736 from 2940 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 14:
The number 342 fits into 2040 5 times, leaving a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 238122.254385
If we take 1710 away from 2040, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 15:
342 can be fit into 3300 9 times, resulting in a remainder of 222.
Record the quotient 9 as the next digit in the result. 
Result so far: 238122.2543859
If we take 3078 away from 3300, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 16:
342 can be fit into 2220 6 times, resulting in a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 238122.25438596
Deduct 2052 from 2220 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 238122.25438596 with a remaining 1.68e-07.
