We look at the division of 54691776 by 407 
The aim is to understand the frequency of 407 in 54691776.

Moving on to step 1:
407 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 407

Going ahead to step 2:
When dividing 54 by 407, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 407

Moving on to step 3:
The number 407 fits into 546 1 times, leaving a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 407 from 546 and we're left with 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 407

On to step 4:
The number 407 fits into 1399 3 times, leaving a remainder of 178.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1221 from 1399 leaves us with 178.
Take the next digit (1) from the dividend and append it to 178, then repeat: 1781 / 407

Moving on to step 5:
The number 407 fits into 1781 4 times, leaving a remainder of 153.
Use 4 as the next digit of our solution. 
Result so far: 134.0
Subtracting 1628 from 1781 leaves us with 153.
Bring next digit (7) of the dividend behind the 153 and repeat the process: 1537 / 407

Let's proceed to step 6:
If we divide 1537 by 407, we get 3 and a remainder of 316.
The number 3 becomes the next digit in our result. 
Result so far: 1343.0
Deduct 1221 from 1537 and we're left with 316.
Take the next digit (7) from the dividend and append it to 316, then repeat: 3167 / 407

Advancing to step 7:
If we divide 3167 by 407, we get 7 and a remainder of 318.
Use 7 as the next digit of our solution. 
Result so far: 13437.0
Subtract 2849 from 3167 to get 318.
Fetch the next digit (6) from the dividend, attach it to 318 and continue: 3186 / 407

Advancing to step 8:
407 can be fit into 3186 7 times, resulting in a remainder of 337.
Record the quotient 7 as the next digit in the result. 
Result so far: 134377.0
If we subtract 2849 from 3186, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 9:
407 goes into 3370 8 times with a remainder of 114.
Write down 8 as next digit of the result. 
Result so far: 134377.8
If we take 3256 away from 3370, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 10:
When dividing 1140 by 407, we get 2 with a remainder of 326.
Write down 2 as next digit of the result. 
Result so far: 134377.82
If we take 814 away from 1140, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 11:
407 can be fit into 3260 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 134377.828
Subtract 3256 from 3260 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
The number 407 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 134377.828
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 407 is 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 134377.828
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 134377.828, and the remainder is 0.0004.
