We divide 55688960 by 638
The aim is to understand the frequency of 638 in 55688960.

Step 1:
638 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 638

Advancing to step 2:
55 divided by 638 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 638

Let's proceed to step 3:
556 divided by 638 is 0 with a remainder of 556.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 556 leaves us with 556.
Take the next digit (8) from the dividend and append it to 556, then repeat: 5568 / 638

Advancing to step 4:
5568 divided by 638 is 8 with a remainder of 464.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5104 from 5568 and we're left with 464.
Append the next digit (8) from the dividend to 464 and continue with: 4648 / 638

Step 5:
638 goes into 4648 7 times with a remainder of 182.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 182 after subtracting 4466 from 4648.
Fetch the next digit (9) from the dividend, attach it to 182 and continue: 1829 / 638

Advancing to step 6:
When dividing 1829 by 638, we get 2 with a remainder of 553.
Put 2 as the next digit of the answer. 
Result so far: 872.0
Deduct 1276 from 1829 and we're left with 553.
Grab the next digit (6) from the dividend, add it to 553, then carry on: 5536 / 638

Step 7:
638 can be fit into 5536 8 times, resulting in a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 8728.0
The remainder is 432 after subtracting 5104 from 5536.
Take the next digit (0) from the dividend and append it to 432, then repeat: 4320 / 638

Advancing to step 8:
If we divide 4320 by 638, we get 6 and a remainder of 492.
Put 6 as the next digit of the answer. 
Result so far: 87286.0
If we subtract 3828 from 4320, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 9:
If we divide 4920 by 638, we get 7 and a remainder of 454.
Use 7 as the next digit of our solution. 
Result so far: 87286.7
If we subtract 4466 from 4920, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 10:
The number 638 fits into 4540 7 times, leaving a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 87286.77
Deduct 4466 from 4540 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 87286.77 with a remainder of 0.074.
