54830351 divided by 638 
The aim is to understand the frequency of 638 in 54830351.

Advancing to step 1:
5 divided by 638 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 638

On to step 2:
When dividing 54 by 638, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 638

Going ahead to step 3:
638 can be fit into 548 0 times, resulting in a remainder of 548.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 548, we end up with 548.
Fetch the next digit (3) from the dividend, attach it to 548 and continue: 5483 / 638

Going ahead to step 4:
638 goes into 5483 8 times with a remainder of 379.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5104 from 5483 leaves us with 379.
Include the next digit (0) from the dividend after 379, then repeat: 3790 / 638

Going ahead to step 5:
638 goes into 3790 5 times with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 600 after subtracting 3190 from 3790.
Include the next digit (3) from the dividend after 600, then repeat: 6003 / 638

Step 6:
If we divide 6003 by 638, we get 9 and a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Subtract 5742 from 6003 to get 261.
Bring next digit (5) of the dividend behind the 261 and repeat the process: 2615 / 638

Going ahead to step 7:
When dividing 2615 by 638, we get 4 with a remainder of 63.
Write down 4 as next digit of the result. 
Result so far: 8594.0
Subtracting 2552 from 2615 leaves us with 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 638

Moving on to step 8:
631 divided by 638 is 0 with a remainder of 631.
The next digit of our result is 0. 
Result so far: 85940.0
Subtract 0 from 631 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Advancing to step 9:
6310 divided by 638 is 9 with a remainder of 568.
Write down 9 as next digit of the result. 
Result so far: 85940.9
Subtracting 5742 from 6310 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 10:
638 can be fit into 5680 8 times, resulting in a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 85940.98
The remainder is 576 after subtracting 5104 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 11:
638 can be fit into 5760 9 times, resulting in a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 85940.989
If we take 5742 away from 5760, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
180 divided by 638 is 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 85940.989
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
638 can be fit into 1800 2 times, resulting in a remainder of 524.
The next digit of our result is 2. 
Result so far: 85940.98902
If we take 1276 away from 1800, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 14:
When dividing 5240 by 638, we get 8 with a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 85940.989028
If we subtract 5104 from 5240, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 15:
638 can be fit into 1360 2 times, resulting in a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 85940.9890282
Deduct 1276 from 1360 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 16:
When dividing 840 by 638, we get 1 with a remainder of 202.
The next digit of our result is 1. 
Result so far: 85940.98902821
Subtracting 638 from 840 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Our division results in 85940.98902821 with a remaining 2.02e-07.
