We look at the division of 89838744 by 638 
The aim is to understand the frequency of 638 in 89838744.

Step 1:
638 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 638

Step 2:
638 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Grab the next digit (8) from the dividend, add it to 89, then carry on: 898 / 638

Going ahead to step 3:
898 divided by 638 is 1 with a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 638 from 898, we get 260.
Take the next digit (3) from the dividend and append it to 260, then repeat: 2603 / 638

Advancing to step 4:
The number 638 fits into 2603 4 times, leaving a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2552 from 2603 and we're left with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 638

On to step 5:
If we divide 518 by 638, we get 0 and a remainder of 518.
The number 0 becomes the next digit in our result. 
Result so far: 140.0
If we subtract 0 from 518, we get 518.
Include the next digit (7) from the dividend after 518, then repeat: 5187 / 638

Moving on to step 6:
638 can be fit into 5187 8 times, resulting in a remainder of 83.
The next digit of our result is 8. 
Result so far: 1408.0
The remainder is 83 after subtracting 5104 from 5187.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 638

On to step 7:
When dividing 834 by 638, we get 1 with a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 14081.0
If we take 638 away from 834, we end up with 196.
Append the next digit (4) from the dividend to 196 and continue with: 1964 / 638

Step 8:
The number 638 fits into 1964 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 140813.0
Deduct 1914 from 1964 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 638, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 140813.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 10:
638 goes into 5000 7 times with a remainder of 534.
Put 7 as the next digit of the answer. 
Result so far: 140813.07
Subtracting 4466 from 5000 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 11:
If we divide 5340 by 638, we get 8 and a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 140813.078
The remainder is 236 after subtracting 5104 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 12:
2360 divided by 638 is 3 with a remainder of 446.
Write down 3 as next digit of the result. 
Result so far: 140813.0783
If we take 1914 away from 2360, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 13:
If we divide 4460 by 638, we get 6 and a remainder of 632.
The next digit of our result is 6. 
Result so far: 140813.07836
The remainder is 632 after subtracting 3828 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 14:
If we divide 6320 by 638, we get 9 and a remainder of 578.
The next digit of our result is 9. 
Result so far: 140813.078369
Subtracting 5742 from 6320 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 15:
When dividing 5780 by 638, we get 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 140813.0783699
If we subtract 5742 from 5780, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 140813.0783699 with a balance of 3.8e-07.
