We're dividing 70082891 by 345 
The aim is to understand the frequency of 345 in 70082891.

On to step 1:
345 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 345

Let's proceed to step 2:
When dividing 70 by 345, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 345

Going ahead to step 3:
345 can be fit into 700 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 690 from 700 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 345

Step 4:
108 divided by 345 is 0 with a remainder of 108.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 108, we get 108.
Append the next digit (2) from the dividend to 108 and continue with: 1082 / 345

Advancing to step 5:
The number 345 fits into 1082 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Subtract 1035 from 1082 to get 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 345

Moving on to step 6:
When dividing 478 by 345, we get 1 with a remainder of 133.
The number 1 becomes the next digit in our result. 
Result so far: 2031.0
Deduct 345 from 478 and we're left with 133.
Bring next digit (9) of the dividend behind the 133 and repeat the process: 1339 / 345

Let's proceed to step 7:
345 can be fit into 1339 3 times, resulting in a remainder of 304.
Use 3 as the next digit of our solution. 
Result so far: 20313.0
The remainder is 304 after subtracting 1035 from 1339.
Grab the next digit (1) from the dividend, add it to 304, then carry on: 3041 / 345

Step 8:
3041 divided by 345 is 8 with a remainder of 281.
Record the quotient 8 as the next digit in the result. 
Result so far: 203138.0
If we subtract 2760 from 3041, we 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.

Step 9:
If we divide 2810 by 345, we get 8 and a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 203138.8
Subtracting 2760 from 2810 leaves us with 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 10:
The number 345 fits into 500 1 times, leaving a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 203138.81
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.

Step 11:
When dividing 1550 by 345, we get 4 with a remainder of 170.
The number 4 becomes the next digit in our result. 
Result so far: 203138.814
Deduct 1380 from 1550 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 12:
1700 divided by 345 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 203138.8144
If we take 1380 away from 1700, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 203138.8144 and a remainder of 0.0032.
