Let's divide 53599843 by 802
The aim is to understand the frequency of 802 in 53599843.

On to step 1:
802 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 802

Step 2:
If we divide 53 by 802, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 802

Let's proceed to step 3:
802 can be fit into 535 0 times, resulting in a remainder of 535.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 535, we end up with 535.
Include the next digit (9) from the dividend after 535, then repeat: 5359 / 802

Step 4:
When dividing 5359 by 802, we get 6 with a remainder of 547.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4812 from 5359 and we're left with 547.
Fetch the next digit (9) from the dividend, attach it to 547 and continue: 5479 / 802

On to step 5:
When dividing 5479 by 802, we get 6 with a remainder of 667.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 4812 from 5479 leaves us with 667.
Take the next digit (8) from the dividend and append it to 667, then repeat: 6678 / 802

Step 6:
6678 divided by 802 is 8 with a remainder of 262.
The next digit of our result is 8. 
Result so far: 668.0
If we take 6416 away from 6678, we end up with 262.
Include the next digit (4) from the dividend after 262, then repeat: 2624 / 802

On to step 7:
802 goes into 2624 3 times with a remainder of 218.
Put 3 as the next digit of the answer. 
Result so far: 6683.0
Deduct 2406 from 2624 and we're left with 218.
Append the next digit (3) from the dividend to 218 and continue with: 2183 / 802

Step 8:
2183 divided by 802 is 2 with a remainder of 579.
Record the quotient 2 as the next digit in the result. 
Result so far: 66832.0
Subtracting 1604 from 2183 leaves us with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 9:
When dividing 5790 by 802, we get 7 with a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 66832.7
Deduct 5614 from 5790 and we're left 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 10:
If we divide 1760 by 802, we get 2 and a remainder of 156.
Use 2 as the next digit of our solution. 
Result so far: 66832.72
Subtract 1604 from 1760 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
1560 divided by 802 is 1 with a remainder of 758.
Record the quotient 1 as the next digit in the result. 
Result so far: 66832.721
Deduct 802 from 1560 and we're left with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Going ahead to step 12:
The number 802 fits into 7580 9 times, leaving a remainder of 362.
Record the quotient 9 as the next digit in the result. 
Result so far: 66832.7219
Subtracting 7218 from 7580 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 13:
802 goes into 3620 4 times with a remainder of 412.
Put 4 as the next digit of the answer. 
Result so far: 66832.72194
The remainder is 412 after subtracting 3208 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 14:
The number 802 fits into 4120 5 times, leaving a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 66832.721945
Subtract 4010 from 4120 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 15:
1100 divided by 802 is 1 with a remainder of 298.
Put 1 as the next digit of the answer. 
Result so far: 66832.7219451
If we subtract 802 from 1100, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 16:
The number 802 fits into 2980 3 times, leaving a remainder of 574.
The number 3 becomes the next digit in our result. 
Result so far: 66832.72194513
The remainder is 574 after subtracting 2406 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

In conclusion, the division gives 66832.72194513 with a balance of 5.74e-07.
