978422 ÷ 84 
We want to figure out the number of times 978422 can be divided by 84.

Advancing to step 1:
9 divided by 84 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 84

Advancing to step 2:
84 can be fit into 97 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 84 from 97, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 84

Going ahead to step 3:
If we divide 138 by 84, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 84 from 138 to get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 84

Going ahead to step 4:
If we divide 544 by 84, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 116.0
Deduct 504 from 544 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 84

Advancing to step 5:
If we divide 402 by 84, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 1164.0
Subtracting 336 from 402 leaves us with 66.
Fetch the next digit (2) from the dividend, attach it to 66 and continue: 662 / 84

Moving on to step 6:
84 goes into 662 7 times with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 11647.0
The remainder is 74 after subtracting 588 from 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 7:
If we divide 740 by 84, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 11647.8
If we subtract 672 from 740, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11647.88
If we take 672 away from 680, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 11647.88 with a remaining 0.008.
