Let's divide 26389464 by 538
The aim is to understand the frequency of 538 in 26389464.

Advancing to step 1:
If we divide 2 by 538, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 538

On to step 2:
If we divide 26 by 538, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 538

Going ahead to step 3:
If we divide 263 by 538, we get 0 and a remainder of 263.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 263 to get 263.
Append the next digit (8) from the dividend to 263 and continue with: 2638 / 538

Going ahead to step 4:
When dividing 2638 by 538, we get 4 with a remainder of 486.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 2152 from 2638 to get 486.
Grab the next digit (9) from the dividend, add it to 486, then carry on: 4869 / 538

Step 5:
When dividing 4869 by 538, we get 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 27 after subtracting 4842 from 4869.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 538

On to step 6:
274 divided by 538 is 0 with a remainder of 274.
Use 0 as the next digit of our solution. 
Result so far: 490.0
If we take 0 away from 274, we end up with 274.
Fetch the next digit (6) from the dividend, attach it to 274 and continue: 2746 / 538

Going ahead to step 7:
538 goes into 2746 5 times with a remainder of 56.
The next digit of our result is 5. 
Result so far: 4905.0
The remainder is 56 after subtracting 2690 from 2746.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 538

Going ahead to step 8:
When dividing 564 by 538, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 49051.0
Subtract 538 from 564 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
538 goes into 260 0 times with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 49051.0
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
538 can be fit into 2600 4 times, resulting in a remainder of 448.
The next digit of our result is 4. 
Result so far: 49051.04
If we subtract 2152 from 2600, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 11:
The number 538 fits into 4480 8 times, leaving a remainder of 176.
The next digit of our result is 8. 
Result so far: 49051.048
If we take 4304 away from 4480, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 12:
When dividing 1760 by 538, we get 3 with a remainder of 146.
Put 3 as the next digit of the answer. 
Result so far: 49051.0483
Subtract 1614 from 1760 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 13:
1460 divided by 538 is 2 with a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 49051.04832
If we subtract 1076 from 1460, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 14:
If we divide 3840 by 538, we get 7 and a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 49051.048327
Subtract 3766 from 3840 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 15:
The number 538 fits into 740 1 times, leaving a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 49051.0483271
The remainder is 202 after subtracting 538 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 16:
When dividing 2020 by 538, we get 3 with a remainder of 406.
Put 3 as the next digit of the answer. 
Result so far: 49051.04832713
Deduct 1614 from 2020 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

The final result is 49051.04832713 with a remainder of 4.06e-07.
