We divide 78409456 by 53
The aim is to understand the frequency of 53 in 78409456.

Step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 53

Advancing to step 2:
53 can be fit into 78 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 53 away from 78, we end up with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 53

On to step 3:
If we divide 254 by 53, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 42 after subtracting 212 from 254.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 53

Step 4:
When dividing 420 by 53, we get 7 with a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 147.0
Subtracting 371 from 420 leaves us with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 53

Going ahead to step 5:
499 divided by 53 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 1479.0
Subtract 477 from 499 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 53

Going ahead to step 6:
224 divided by 53 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 14794.0
If we take 212 away from 224, we end up with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 53

Let's proceed to step 7:
The number 53 fits into 125 2 times, leaving a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 147942.0
If we subtract 106 from 125, we get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 53

Advancing to step 8:
When dividing 196 by 53, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 1479423.0
If we take 159 away from 196, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
The number 53 fits into 370 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 1479423.6
If we subtract 318 from 370, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
53 goes into 520 9 times with a remainder of 43.
The next digit of our result is 9. 
Result so far: 1479423.69
If we take 477 away from 520, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 11:
If we divide 430 by 53, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1479423.698
Subtracting 424 from 430 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
53 can be fit into 60 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1479423.6981
Subtracting 53 from 60 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
When dividing 70 by 53, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1479423.69811
Deduct 53 from 70 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 1479423.69811 with a remainder of 1.7e-05.
