We look at the division of 34587830 by 345 
The aim is to understand the frequency of 345 in 34587830.

Going ahead to step 1:
3 divided by 345 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 345

Going ahead to step 2:
34 divided by 345 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 345

Advancing to step 3:
345 can be fit into 345 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 345 from 345 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 345

Advancing to step 4:
When dividing 8 by 345, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 345

Going ahead to step 5:
If we divide 87 by 345, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 345

Going ahead to step 6:
If we divide 878 by 345, we get 2 and a remainder of 188.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
The remainder is 188 after subtracting 690 from 878.
Fetch the next digit (3) from the dividend, attach it to 188 and continue: 1883 / 345

On to step 7:
If we divide 1883 by 345, we get 5 and a remainder of 158.
Write down 5 as next digit of the result. 
Result so far: 10025.0
Deduct 1725 from 1883 and we're left with 158.
Take the next digit (0) from the dividend and append it to 158, then repeat: 1580 / 345

On to step 8:
The number 345 fits into 1580 4 times, leaving a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 100254.0
If we subtract 1380 from 1580, we 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.

On to step 9:
When dividing 2000 by 345, we get 5 with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 100254.5
The remainder is 275 after subtracting 1725 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
When dividing 2750 by 345, we get 7 with a remainder of 335.
Record the quotient 7 as the next digit in the result. 
Result so far: 100254.57
If we subtract 2415 from 2750, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 11:
The number 345 fits into 3350 9 times, leaving a remainder of 245.
The next digit of our result is 9. 
Result so far: 100254.579
If we subtract 3105 from 3350, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 12:
345 can be fit into 2450 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 100254.5797
Subtracting 2415 from 2450 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
If we divide 350 by 345, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 100254.57971
Subtract 345 from 350 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
When dividing 50 by 345, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 100254.57971
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
345 goes into 500 1 times with a remainder of 155.
The next digit of our result is 1. 
Result so far: 100254.5797101
If we subtract 345 from 500, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 16:
The number 345 fits into 1550 4 times, leaving a remainder of 170.
The number 4 becomes the next digit in our result. 
Result so far: 100254.57971014
If we subtract 1380 from 1550, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 100254.57971014 with a balance of 1.7e-07.
