We divide 42588790 by 78
The aim is to understand the frequency of 78 in 42588790.

Moving on to step 1:
The number 78 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 78

Moving on to step 2:
78 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 78

On to step 3:
425 divided by 78 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 35 after subtracting 390 from 425.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 78

Let's proceed to step 4:
78 goes into 358 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Subtracting 312 from 358 leaves us with 46.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 78

Step 5:
When dividing 468 by 78, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 546.0
Subtracting 468 from 468 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 78

Going ahead to step 6:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 5460.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 78

On to step 7:
The number 78 fits into 79 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 54601.0
Subtracting 78 from 79 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 78

On to step 8:
10 divided by 78 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 546010.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 546010.1
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 546010.12
Subtract 156 from 220 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 11:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 546010.128
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 78, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 546010.1282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
78 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 546010.1282
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
When dividing 400 by 78, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 546010.128205
Subtracting 390 from 400 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
78 goes into 100 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 546010.1282051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 16:
78 goes into 220 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 546010.12820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 546010.12820512 with a remainder of 6.4e-08.
