We look at the division of 55493807 by 440 
The aim is to understand the frequency of 440 in 55493807.

On to step 1:
When dividing 5 by 440, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 440

Step 2:
440 can be fit into 55 0 times, resulting in a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 440

Step 3:
If we divide 554 by 440, we get 1 and a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 440 from 554 to get 114.
Include the next digit (9) from the dividend after 114, then repeat: 1149 / 440

Going ahead to step 4:
If we divide 1149 by 440, we get 2 and a remainder of 269.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 880 away from 1149, we end up with 269.
Append the next digit (3) from the dividend to 269 and continue with: 2693 / 440

On to step 5:
440 goes into 2693 6 times with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 2640 from 2693 to get 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 440

Let's proceed to step 6:
538 divided by 440 is 1 with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 1261.0
Subtract 440 from 538 to get 98.
Bring next digit (0) of the dividend behind the 98 and repeat the process: 980 / 440

On to step 7:
The number 440 fits into 980 2 times, leaving a remainder of 100.
The next digit of our result is 2. 
Result so far: 12612.0
If we take 880 away from 980, we end up with 100.
Grab the next digit (7) from the dividend, add it to 100, then carry on: 1007 / 440

Step 8:
When dividing 1007 by 440, we get 2 with a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 126122.0
If we subtract 880 from 1007, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
When dividing 1270 by 440, we get 2 with a remainder of 390.
Use 2 as the next digit of our solution. 
Result so far: 126122.2
Subtract 880 from 1270 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
When dividing 3900 by 440, we get 8 with a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 126122.28
Subtracting 3520 from 3900 leaves us with 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:
If we divide 3800 by 440, we get 8 and a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 126122.288
Deduct 3520 from 3800 and we're left 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.

The quotient of the division is 126122.288, and the remainder is 0.028.
