We're dividing 89343468 by 172 
The aim is to understand the frequency of 172 in 89343468.

Moving on to step 1:
The number 172 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 172

Moving on to step 2:
The number 172 fits into 89 0 times, leaving a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (3) from the dividend, attach it to 89 and continue: 893 / 172

Going ahead to step 3:
172 goes into 893 5 times with a remainder of 33.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 860 from 893, we get 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 172

Step 4:
When dividing 334 by 172, we get 1 with a remainder of 162.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 172 from 334 and we're left with 162.
Include the next digit (3) from the dividend after 162, then repeat: 1623 / 172

On to step 5:
The number 172 fits into 1623 9 times, leaving a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 519.0
Subtract 1548 from 1623 to get 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 172

Let's proceed to step 6:
172 goes into 754 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 5194.0
If we take 688 away from 754, we end up with 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 172

Step 7:
When dividing 666 by 172, we get 3 with a remainder of 150.
The next digit of our result is 3. 
Result so far: 51943.0
If we subtract 516 from 666, we get 150.
Grab the next digit (8) from the dividend, add it to 150, then carry on: 1508 / 172

Let's proceed to step 8:
172 goes into 1508 8 times with a remainder of 132.
The next digit of our result is 8. 
Result so far: 519438.0
If we take 1376 away from 1508, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 9:
172 goes into 1320 7 times with a remainder of 116.
Put 7 as the next digit of the answer. 
Result so far: 519438.7
Deduct 1204 from 1320 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
172 can be fit into 1160 6 times, resulting in a remainder of 128.
Write down 6 as next digit of the result. 
Result so far: 519438.76
Subtracting 1032 from 1160 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 11:
When dividing 1280 by 172, we get 7 with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 519438.767
If we subtract 1204 from 1280, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
When dividing 760 by 172, we get 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 519438.7674
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
When dividing 720 by 172, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 519438.76744
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 519438.76744, with a leftover of 3.2e-05.
