68423018 ÷ 170 
The aim is to understand the frequency of 170 in 68423018.

Let's proceed to step 1:
170 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 170

Advancing to step 2:
68 divided by 170 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 170

Step 3:
The number 170 fits into 684 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 680 from 684 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 170

Let's proceed to step 4:
If we divide 42 by 170, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 170

On to step 5:
423 divided by 170 is 2 with a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 402.0
Deduct 340 from 423 and we're left with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 170

Step 6:
170 goes into 830 4 times with a remainder of 150.
The next digit of our result is 4. 
Result so far: 4024.0
If we take 680 away from 830, we end up with 150.
Fetch the next digit (1) from the dividend, attach it to 150 and continue: 1501 / 170

Let's proceed to step 7:
When dividing 1501 by 170, we get 8 with a remainder of 141.
Use 8 as the next digit of our solution. 
Result so far: 40248.0
Subtracting 1360 from 1501 leaves us with 141.
Append the next digit (8) from the dividend to 141 and continue with: 1418 / 170

Let's proceed to step 8:
170 goes into 1418 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 402488.0
Subtract 1360 from 1418 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
580 divided by 170 is 3 with a remainder of 70.
The next digit of our result is 3. 
Result so far: 402488.3
Deduct 510 from 580 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
The number 170 fits into 700 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 402488.34
Subtracting 680 from 700 leaves us 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.

Going ahead to step 11:
When dividing 200 by 170, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 402488.341
If we subtract 170 from 200, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
The number 170 fits into 300 1 times, leaving a remainder of 130.
Record the quotient 1 as the next digit in the result. 
Result so far: 402488.3411
If we take 170 away from 300, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 402488.3411 with a remaining 0.0013.
