We look at the division of 99271688 by 456 
The aim is to understand the frequency of 456 in 99271688.

Going ahead to step 1:
If we divide 9 by 456, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 456

Let's proceed to step 2:
99 divided by 456 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 456

On to step 3:
The number 456 fits into 992 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 912 from 992, we get 80.
Append the next digit (7) from the dividend to 80 and continue with: 807 / 456

Advancing to step 4:
456 goes into 807 1 times with a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 351 after subtracting 456 from 807.
Include the next digit (1) from the dividend after 351, then repeat: 3511 / 456

Let's proceed to step 5:
The number 456 fits into 3511 7 times, leaving a remainder of 319.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtract 3192 from 3511 to get 319.
Include the next digit (6) from the dividend after 319, then repeat: 3196 / 456

Moving on to step 6:
456 can be fit into 3196 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2177.0
Subtract 3192 from 3196 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 456

On to step 7:
48 divided by 456 is 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 21770.0
If we take 0 away from 48, we end up with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 456

On to step 8:
When dividing 488 by 456, we get 1 with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 217701.0
Subtracting 456 from 488 leaves us 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.

Step 9:
456 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 217701.0
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
456 goes into 3200 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 217701.07
Deduct 3192 from 3200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
456 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 217701.07
If we take 0 away from 80, we end up 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 12:
The number 456 fits into 800 1 times, leaving a remainder of 344.
The next digit of our result is 1. 
Result so far: 217701.0701
Subtract 456 from 800 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 13:
If we divide 3440 by 456, we get 7 and a remainder of 248.
Put 7 as the next digit of the answer. 
Result so far: 217701.07017
The remainder is 248 after subtracting 3192 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 14:
The number 456 fits into 2480 5 times, leaving a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 217701.070175
Deduct 2280 from 2480 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 15:
When dividing 2000 by 456, we get 4 with a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 217701.0701754
Subtract 1824 from 2000 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 16:
The number 456 fits into 1760 3 times, leaving a remainder of 392.
Use 3 as the next digit of our solution. 
Result so far: 217701.07017543
Subtract 1368 from 1760 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

After the division, we end up with 217701.07017543 and a remainder of 3.92e-07.
