12976830 ÷ 172 
The aim is to understand the frequency of 172 in 12976830.

On to step 1:
172 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 172

Let's proceed to step 2:
172 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 172

Let's proceed to step 3:
When dividing 129 by 172, we get 0 with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 172

Step 4:
172 can be fit into 1297 7 times, resulting in a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 1204 from 1297, we get 93.
Fetch the next digit (6) from the dividend, attach it to 93 and continue: 936 / 172

Moving on to step 5:
The number 172 fits into 936 5 times, leaving a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 860 from 936, we get 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 172

On to step 6:
If we divide 768 by 172, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 754.0
Subtracting 688 from 768 leaves us with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 172

Let's proceed to step 7:
If we divide 803 by 172, we get 4 and a remainder of 115.
The number 4 becomes the next digit in our result. 
Result so far: 7544.0
Subtracting 688 from 803 leaves us with 115.
Grab the next digit (0) from the dividend, add it to 115, then carry on: 1150 / 172

Moving on to step 8:
172 can be fit into 1150 6 times, resulting in a remainder of 118.
Put 6 as the next digit of the answer. 
Result so far: 75446.0
The remainder is 118 after subtracting 1032 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 9:
If we divide 1180 by 172, we get 6 and a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 75446.6
If we subtract 1032 from 1180, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 10:
1480 divided by 172 is 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 75446.68
Subtract 1376 from 1480 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
172 can be fit into 1040 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 75446.686
If we subtract 1032 from 1040, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
172 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 75446.686
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
172 can be fit into 800 4 times, resulting in a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 75446.68604
If we take 688 away from 800, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 14:
172 goes into 1120 6 times with a remainder of 88.
The number 6 becomes the next digit in our result. 
Result so far: 75446.686046
Subtract 1032 from 1120 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 15:
172 can be fit into 880 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 75446.6860465
If we take 860 away from 880, we end up 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.

On to step 16:
172 can be fit into 200 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 75446.68604651
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 75446.68604651, and the remainder is 2.8e-08.
