2989778 divided by 422 
The aim is to understand the frequency of 422 in 2989778.

Moving on to step 1:
If we divide 2 by 422, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 422

Step 2:
422 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 422

Moving on to step 3:
422 goes into 298 0 times with a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 298 and we're left with 298.
Take the next digit (9) from the dividend and append it to 298, then repeat: 2989 / 422

Let's proceed to step 4:
422 can be fit into 2989 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 2954 from 2989 leaves us with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 422

On to step 5:
If we divide 357 by 422, we get 0 and a remainder of 357.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
If we subtract 0 from 357, we get 357.
Take the next digit (7) from the dividend and append it to 357, then repeat: 3577 / 422

Moving on to step 6:
If we divide 3577 by 422, we get 8 and a remainder of 201.
Use 8 as the next digit of our solution. 
Result so far: 708.0
Subtract 3376 from 3577 to get 201.
Grab the next digit (8) from the dividend, add it to 201, then carry on: 2018 / 422

Step 7:
If we divide 2018 by 422, we get 4 and a remainder of 330.
Record the quotient 4 as the next digit in the result. 
Result so far: 7084.0
The remainder is 330 after subtracting 1688 from 2018.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 8:
The number 422 fits into 3300 7 times, leaving a remainder of 346.
The number 7 becomes the next digit in our result. 
Result so far: 7084.7
Subtract 2954 from 3300 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 9:
The number 422 fits into 3460 8 times, leaving a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 7084.78
Deduct 3376 from 3460 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
When dividing 840 by 422, we get 1 with a remainder of 418.
Write down 1 as next digit of the result. 
Result so far: 7084.781
The remainder is 418 after subtracting 422 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 11:
The number 422 fits into 4180 9 times, leaving a remainder of 382.
Write down 9 as next digit of the result. 
Result so far: 7084.7819
The remainder is 382 after subtracting 3798 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 12:
422 goes into 3820 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 7084.78199
The remainder is 22 after subtracting 3798 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 7084.78199, with a leftover of 2.2e-05.
