83581736 divided by 172 
The aim is to understand the frequency of 172 in 83581736.

Let's proceed to step 1:
172 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 172

Step 2:
172 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 172

Step 3:
The number 172 fits into 835 4 times, leaving a remainder of 147.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 688 from 835 and we're left with 147.
Bring next digit (8) of the dividend behind the 147 and repeat the process: 1478 / 172

Advancing to step 4:
172 goes into 1478 8 times with a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 1376 from 1478 and we're left with 102.
Bring next digit (1) of the dividend behind the 102 and repeat the process: 1021 / 172

Let's proceed to step 5:
The number 172 fits into 1021 5 times, leaving a remainder of 161.
Use 5 as the next digit of our solution. 
Result so far: 485.0
Deduct 860 from 1021 and we're left with 161.
Fetch the next digit (7) from the dividend, attach it to 161 and continue: 1617 / 172

Step 6:
If we divide 1617 by 172, we get 9 and a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 4859.0
The remainder is 69 after subtracting 1548 from 1617.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 172

On to step 7:
172 goes into 693 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 48594.0
Subtracting 688 from 693 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 172

Let's proceed to step 8:
The number 172 fits into 56 0 times, leaving a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 485940.0
The remainder is 56 after subtracting 0 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
172 goes into 560 3 times with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 485940.3
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
172 can be fit into 440 2 times, resulting in a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 485940.32
The remainder is 96 after subtracting 344 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
960 divided by 172 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 485940.325
If we take 860 away from 960, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 12:
When dividing 1000 by 172, we get 5 with a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 485940.3255
Subtracting 860 from 1000 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 485940.3255 with a remainder of 0.0014.
