20342113 ÷ 345 
The aim is to understand the frequency of 345 in 20342113.

Advancing to step 1:
When dividing 2 by 345, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 345

Step 2:
345 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 345

On to step 3:
The number 345 fits into 203 0 times, leaving a remainder of 203.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 203 leaves us with 203.
Include the next digit (4) from the dividend after 203, then repeat: 2034 / 345

Moving on to step 4:
The number 345 fits into 2034 5 times, leaving a remainder of 309.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 309 after subtracting 1725 from 2034.
Fetch the next digit (2) from the dividend, attach it to 309 and continue: 3092 / 345

On to step 5:
If we divide 3092 by 345, we get 8 and a remainder of 332.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 2760 from 3092 to get 332.
Append the next digit (1) from the dividend to 332 and continue with: 3321 / 345

Let's proceed to step 6:
When dividing 3321 by 345, we get 9 with a remainder of 216.
Put 9 as the next digit of the answer. 
Result so far: 589.0
If we subtract 3105 from 3321, we get 216.
Bring next digit (1) of the dividend behind the 216 and repeat the process: 2161 / 345

Let's proceed to step 7:
If we divide 2161 by 345, we get 6 and a remainder of 91.
The next digit of our result is 6. 
Result so far: 5896.0
If we take 2070 away from 2161, we end up with 91.
Grab the next digit (3) from the dividend, add it to 91, then carry on: 913 / 345

On to step 8:
345 can be fit into 913 2 times, resulting in a remainder of 223.
Use 2 as the next digit of our solution. 
Result so far: 58962.0
If we subtract 690 from 913, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 9:
2230 divided by 345 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 58962.6
Subtracting 2070 from 2230 leaves us 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.

On to step 10:
345 goes into 1600 4 times with a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 58962.64
If we subtract 1380 from 1600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
If we divide 2200 by 345, we get 6 and a remainder of 130.
Put 6 as the next digit of the answer. 
Result so far: 58962.646
The remainder is 130 after subtracting 2070 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
345 can be fit into 1300 3 times, resulting in a remainder of 265.
Use 3 as the next digit of our solution. 
Result so far: 58962.6463
If we take 1035 away from 1300, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 13:
The number 345 fits into 2650 7 times, leaving a remainder of 235.
Use 7 as the next digit of our solution. 
Result so far: 58962.64637
Subtract 2415 from 2650 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 14:
The number 345 fits into 2350 6 times, leaving a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 58962.646376
If we subtract 2070 from 2350, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
The number 345 fits into 2800 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 58962.6463768
Deduct 2760 from 2800 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
When dividing 400 by 345, we get 1 with a remainder of 55.
The next digit of our result is 1. 
Result so far: 58962.64637681
If we subtract 345 from 400, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 58962.64637681 with a remaining 5.5e-08.
