31650070 divided by 78 
The aim is to understand the frequency of 78 in 31650070.

On to step 1:
78 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 78

Step 2:
78 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 78

Going ahead to step 3:
78 goes into 316 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 312 from 316 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 78

Going ahead to step 4:
45 divided by 78 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 78

Going ahead to step 5:
When dividing 450 by 78, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
If we take 390 away from 450, we end up with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 78

Step 6:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 4057.0
If we take 546 away from 600, we end up with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 78

Moving on to step 7:
When dividing 547 by 78, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 40577.0
If we take 546 away from 547, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 78

Let's proceed to step 8:
The number 78 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 405770.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
78 can be fit into 100 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 405770.1
If we take 78 away from 100, we end up 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.

Advancing to step 10:
78 can be fit into 220 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 405770.12
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
The number 78 fits into 640 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 405770.128
Deduct 624 from 640 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
160 divided by 78 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 405770.1282
Subtract 156 from 160 to 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.

Let's proceed to step 13:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 405770.1282
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
When dividing 400 by 78, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 405770.128205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
78 goes into 100 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 405770.1282051
The remainder is 22 after subtracting 78 from 100.
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:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 405770.12820512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 405770.12820512, and the remainder is 6.4e-08.
