77974867 divided by 422 
Our goal is to divide 77974867 by 422.

On to step 1:
422 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 422

Going ahead to step 2:
If we divide 77 by 422, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 422

Step 3:
422 goes into 779 1 times with a remainder of 357.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 357 after subtracting 422 from 779.
Include the next digit (7) from the dividend after 357, then repeat: 3577 / 422

Let's proceed to step 4:
422 can be fit into 3577 8 times, resulting in a remainder of 201.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 201 after subtracting 3376 from 3577.
Grab the next digit (4) from the dividend, add it to 201, then carry on: 2014 / 422

Step 5:
If we divide 2014 by 422, we get 4 and a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 184.0
If we take 1688 away from 2014, we end up with 326.
Append the next digit (8) from the dividend to 326 and continue with: 3268 / 422

Moving on to step 6:
When dividing 3268 by 422, we get 7 with a remainder of 314.
Put 7 as the next digit of the answer. 
Result so far: 1847.0
If we subtract 2954 from 3268, we get 314.
Grab the next digit (6) from the dividend, add it to 314, then carry on: 3146 / 422

On to step 7:
The number 422 fits into 3146 7 times, leaving a remainder of 192.
Use 7 as the next digit of our solution. 
Result so far: 18477.0
If we subtract 2954 from 3146, we get 192.
Include the next digit (7) from the dividend after 192, then repeat: 1927 / 422

Step 8:
The number 422 fits into 1927 4 times, leaving a remainder of 239.
Record the quotient 4 as the next digit in the result. 
Result so far: 184774.0
If we take 1688 away from 1927, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 9:
The number 422 fits into 2390 5 times, leaving a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 184774.5
Subtract 2110 from 2390 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
The number 422 fits into 2800 6 times, leaving a remainder of 268.
The number 6 becomes the next digit in our result. 
Result so far: 184774.56
The remainder is 268 after subtracting 2532 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 11:
2680 divided by 422 is 6 with a remainder of 148.
The next digit of our result is 6. 
Result so far: 184774.566
If we take 2532 away from 2680, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 184774.566, with a leftover of 0.0148.
