We're dividing 54388743 by 802 
The aim is to understand the frequency of 802 in 54388743.

Let's proceed to step 1:
When dividing 5 by 802, we get 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.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 802

On to step 2:
If we divide 54 by 802, we get 0 and a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Fetch the next digit (3) from the dividend, attach it to 54 and continue: 543 / 802

Going ahead to step 3:
802 goes into 543 0 times with a remainder of 543.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 543, we get 543.
Bring next digit (8) of the dividend behind the 543 and repeat the process: 5438 / 802

On to step 4:
When dividing 5438 by 802, we get 6 with a remainder of 626.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4812 from 5438 leaves us with 626.
Bring next digit (8) of the dividend behind the 626 and repeat the process: 6268 / 802

On to step 5:
6268 divided by 802 is 7 with a remainder of 654.
The next digit of our result is 7. 
Result so far: 67.0
If we take 5614 away from 6268, we end up with 654.
Grab the next digit (7) from the dividend, add it to 654, then carry on: 6547 / 802

Step 6:
If we divide 6547 by 802, we get 8 and a remainder of 131.
Put 8 as the next digit of the answer. 
Result so far: 678.0
The remainder is 131 after subtracting 6416 from 6547.
Bring next digit (4) of the dividend behind the 131 and repeat the process: 1314 / 802

Let's proceed to step 7:
802 goes into 1314 1 times with a remainder of 512.
The number 1 becomes the next digit in our result. 
Result so far: 6781.0
Subtracting 802 from 1314 leaves us with 512.
Fetch the next digit (3) from the dividend, attach it to 512 and continue: 5123 / 802

On to step 8:
The number 802 fits into 5123 6 times, leaving a remainder of 311.
Use 6 as the next digit of our solution. 
Result so far: 67816.0
Deduct 4812 from 5123 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 9:
If we divide 3110 by 802, we get 3 and a remainder of 704.
The number 3 becomes the next digit in our result. 
Result so far: 67816.3
The remainder is 704 after subtracting 2406 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 10:
When dividing 7040 by 802, we get 8 with a remainder of 624.
The next digit of our result is 8. 
Result so far: 67816.38
If we subtract 6416 from 7040, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 11:
802 can be fit into 6240 7 times, resulting in a remainder of 626.
Put 7 as the next digit of the answer. 
Result so far: 67816.387
If we take 5614 away from 6240, we end up with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 12:
If we divide 6260 by 802, we get 7 and a remainder of 646.
The next digit of our result is 7. 
Result so far: 67816.3877
Subtract 5614 from 6260 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

After the division, we end up with 67816.3877 and a remainder of 0.00646.
