91982944 ÷ 456 
The aim is to understand the frequency of 456 in 91982944.

Step 1:
If we divide 9 by 456, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 456

Step 2:
If we divide 91 by 456, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (9) from the dividend and append it to 91, then repeat: 919 / 456

Moving on to step 3:
The number 456 fits into 919 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 912 from 919, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 456

Advancing to step 4:
456 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 456

Going ahead to step 5:
456 can be fit into 782 1 times, resulting in a remainder of 326.
Use 1 as the next digit of our solution. 
Result so far: 201.0
If we take 456 away from 782, we end up with 326.
Grab the next digit (9) from the dividend, add it to 326, then carry on: 3269 / 456

Moving on to step 6:
456 goes into 3269 7 times with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 2017.0
The remainder is 77 after subtracting 3192 from 3269.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 456

Going ahead to step 7:
456 goes into 774 1 times with a remainder of 318.
The next digit of our result is 1. 
Result so far: 20171.0
The remainder is 318 after subtracting 456 from 774.
Append the next digit (4) from the dividend to 318 and continue with: 3184 / 456

Let's proceed to step 8:
If we divide 3184 by 456, we get 6 and a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 201716.0
If we subtract 2736 from 3184, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 9:
When dividing 4480 by 456, we get 9 with a remainder of 376.
Write down 9 as next digit of the result. 
Result so far: 201716.9
The remainder is 376 after subtracting 4104 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 10:
If we divide 3760 by 456, we get 8 and a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 201716.98
Subtracting 3648 from 3760 leaves us 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.

Step 11:
1120 divided by 456 is 2 with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 201716.982
Subtracting 912 from 1120 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 12:
The number 456 fits into 2080 4 times, leaving a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 201716.9824
The remainder is 256 after subtracting 1824 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
The number 456 fits into 2560 5 times, leaving a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 201716.98245
If we take 2280 away from 2560, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
If we divide 2800 by 456, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 201716.982456
The remainder is 64 after subtracting 2736 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
640 divided by 456 is 1 with a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 201716.9824561
Deduct 456 from 640 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 16:
If we divide 1840 by 456, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 201716.98245614
If we subtract 1824 from 1840, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 201716.98245614 and a remainder of 1.6e-08.
