We divide 51505331 by 78
The aim is to understand the frequency of 78 in 51505331.

Step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 78

Going ahead to step 2:
When dividing 51 by 78, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 78

On to step 3:
The number 78 fits into 515 6 times, leaving a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 47 after subtracting 468 from 515.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 78

Let's proceed to step 4:
78 goes into 470 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 468 from 470 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 78

Going ahead to step 5:
The number 78 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 660.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 78

Moving on to step 6:
253 divided by 78 is 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 6603.0
The remainder is 19 after subtracting 234 from 253.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 78

Advancing to step 7:
If we divide 193 by 78, we get 2 and a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 66032.0
If we take 156 away from 193, we end up with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 78

On to step 8:
78 goes into 371 4 times with a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 660324.0
Deduct 312 from 371 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
If we divide 590 by 78, we get 7 and a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 660324.7
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
78 goes into 440 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 660324.75
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 660324.756
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
78 goes into 320 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 660324.7564
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
If we divide 80 by 78, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 660324.75641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
When dividing 20 by 78, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 660324.75641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 660324.7564102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 16:
When dividing 440 by 78, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 660324.75641025
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 660324.75641025 with a balance of 5e-08.
