We look at the division of 67660121 by 456 
The aim is to understand the frequency of 456 in 67660121.

Moving on to step 1:
456 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 456

On to step 2:
When dividing 67 by 456, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (6) from the dividend and append it to 67, then repeat: 676 / 456

Advancing to step 3:
When dividing 676 by 456, we get 1 with a remainder of 220.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 220 after subtracting 456 from 676.
Append the next digit (6) from the dividend to 220 and continue with: 2206 / 456

Going ahead to step 4:
456 can be fit into 2206 4 times, resulting in a remainder of 382.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1824 from 2206 to get 382.
Append the next digit (0) from the dividend to 382 and continue with: 3820 / 456

Advancing to step 5:
If we divide 3820 by 456, we get 8 and a remainder of 172.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 3648 from 3820 leaves us with 172.
Grab the next digit (1) from the dividend, add it to 172, then carry on: 1721 / 456

Going ahead to step 6:
When dividing 1721 by 456, we get 3 with a remainder of 353.
Record the quotient 3 as the next digit in the result. 
Result so far: 1483.0
If we subtract 1368 from 1721, we get 353.
Grab the next digit (2) from the dividend, add it to 353, then carry on: 3532 / 456

On to step 7:
3532 divided by 456 is 7 with a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 14837.0
Deduct 3192 from 3532 and we're left with 340.
Bring next digit (1) of the dividend behind the 340 and repeat the process: 3401 / 456

Advancing to step 8:
3401 divided by 456 is 7 with a remainder of 209.
The next digit of our result is 7. 
Result so far: 148377.0
Subtracting 3192 from 3401 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
2090 divided by 456 is 4 with a remainder of 266.
Use 4 as the next digit of our solution. 
Result so far: 148377.4
Deduct 1824 from 2090 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 10:
The number 456 fits into 2660 5 times, leaving a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 148377.45
Subtract 2280 from 2660 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
456 goes into 3800 8 times with a remainder of 152.
The next digit of our result is 8. 
Result so far: 148377.458
The remainder is 152 after subtracting 3648 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 12:
The number 456 fits into 1520 3 times, leaving a remainder of 152.
Record the quotient 3 as the next digit in the result. 
Result so far: 148377.4583
Deduct 1368 from 1520 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 13:
If we divide 1520 by 456, we get 3 and a remainder of 152.
The next digit of our result is 3. 
Result so far: 148377.45833
Subtracting 1368 from 1520 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 148377.45833 with a remaining 0.000152.
