81124621 ÷ 340 
The aim is to understand the frequency of 340 in 81124621.

Advancing to step 1:
The number 340 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 340

Going ahead to step 2:
The number 340 fits into 81 0 times, leaving a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (1) from the dividend to 81 and continue with: 811 / 340

Step 3:
When dividing 811 by 340, we get 2 with a remainder of 131.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 680 from 811 and we're left with 131.
Fetch the next digit (2) from the dividend, attach it to 131 and continue: 1312 / 340

Going ahead to step 4:
340 goes into 1312 3 times with a remainder of 292.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 1020 from 1312 to get 292.
Grab the next digit (4) from the dividend, add it to 292, then carry on: 2924 / 340

On to step 5:
340 goes into 2924 8 times with a remainder of 204.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
Deduct 2720 from 2924 and we're left with 204.
Take the next digit (6) from the dividend and append it to 204, then repeat: 2046 / 340

Moving on to step 6:
The number 340 fits into 2046 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2386.0
Subtracting 2040 from 2046 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 340

Step 7:
When dividing 62 by 340, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 23860.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (1) from the dividend after 62, then repeat: 621 / 340

Step 8:
When dividing 621 by 340, we get 1 with a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 238601.0
Subtract 340 from 621 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Let's proceed to step 9:
When dividing 2810 by 340, we get 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 238601.8
If we subtract 2720 from 2810, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
900 divided by 340 is 2 with a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 238601.82
Deduct 680 from 900 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
The number 340 fits into 2200 6 times, leaving a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 238601.826
If we take 2040 away from 2200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
1600 divided by 340 is 4 with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 238601.8264
Subtracting 1360 from 1600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
340 can be fit into 2400 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 238601.82647
If we take 2380 away from 2400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
When dividing 200 by 340, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 238601.82647
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 15:
340 can be fit into 2000 5 times, resulting in a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 238601.8264705
The remainder is 300 after subtracting 1700 from 2000.
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 16:
If we divide 3000 by 340, we get 8 and a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 238601.82647058
Deduct 2720 from 3000 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 238601.82647058 with a balance of 2.8e-07.
