78871306 divided by 422 
The aim is to understand the frequency of 422 in 78871306.

On to step 1:
7 divided by 422 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 422

Going ahead to step 2:
If we divide 78 by 422, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 422

Advancing to step 3:
The number 422 fits into 788 1 times, leaving a remainder of 366.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 422 from 788, we get 366.
Append the next digit (7) from the dividend to 366 and continue with: 3667 / 422

Let's proceed to step 4:
The number 422 fits into 3667 8 times, leaving a remainder of 291.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 3376 from 3667 to get 291.
Take the next digit (1) from the dividend and append it to 291, then repeat: 2911 / 422

Going ahead to step 5:
422 can be fit into 2911 6 times, resulting in a remainder of 379.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
The remainder is 379 after subtracting 2532 from 2911.
Include the next digit (3) from the dividend after 379, then repeat: 3793 / 422

Step 6:
422 can be fit into 3793 8 times, resulting in a remainder of 417.
Write down 8 as next digit of the result. 
Result so far: 1868.0
The remainder is 417 after subtracting 3376 from 3793.
Bring next digit (0) of the dividend behind the 417 and repeat the process: 4170 / 422

On to step 7:
422 goes into 4170 9 times with a remainder of 372.
Put 9 as the next digit of the answer. 
Result so far: 18689.0
If we take 3798 away from 4170, we end up with 372.
Take the next digit (6) from the dividend and append it to 372, then repeat: 3726 / 422

Moving on to step 8:
422 goes into 3726 8 times with a remainder of 350.
The number 8 becomes the next digit in our result. 
Result so far: 186898.0
Subtracting 3376 from 3726 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 9:
422 goes into 3500 8 times with a remainder of 124.
Write down 8 as next digit of the result. 
Result so far: 186898.8
Deduct 3376 from 3500 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 10:
When dividing 1240 by 422, we get 2 with a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 186898.82
If we take 844 away from 1240, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 11:
If we divide 3960 by 422, we get 9 and a remainder of 162.
Put 9 as the next digit of the answer. 
Result so far: 186898.829
If we take 3798 away from 3960, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 12:
When dividing 1620 by 422, we get 3 with a remainder of 354.
The number 3 becomes the next digit in our result. 
Result so far: 186898.8293
The remainder is 354 after subtracting 1266 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 13:
If we divide 3540 by 422, we get 8 and a remainder of 164.
Use 8 as the next digit of our solution. 
Result so far: 186898.82938
Subtracting 3376 from 3540 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 14:
422 can be fit into 1640 3 times, resulting in a remainder of 374.
The next digit of our result is 3. 
Result so far: 186898.829383
Subtract 1266 from 1640 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 15:
3740 divided by 422 is 8 with a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 186898.8293838
If we subtract 3376 from 3740, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 16:
422 goes into 3640 8 times with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 186898.82938388
If we take 3376 away from 3640, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Our division results in 186898.82938388 with a remaining 2.64e-07.
