84206478 ÷ 192 
We want to figure out the number of times 84206478 can be divided by 192.

Let's proceed to step 1:
192 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 192

Moving on to step 2:
When dividing 84 by 192, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 192

Step 3:
192 can be fit into 842 4 times, resulting in a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 768 from 842 and we're left with 74.
Take the next digit (0) from the dividend and append it to 74, then repeat: 740 / 192

On to step 4:
740 divided by 192 is 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 576 from 740 leaves us with 164.
Append the next digit (6) from the dividend to 164 and continue with: 1646 / 192

Step 5:
192 can be fit into 1646 8 times, resulting in a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 438.0
Subtract 1536 from 1646 to get 110.
Include the next digit (4) from the dividend after 110, then repeat: 1104 / 192

Moving on to step 6:
The number 192 fits into 1104 5 times, leaving a remainder of 144.
Record the quotient 5 as the next digit in the result. 
Result so far: 4385.0
The remainder is 144 after subtracting 960 from 1104.
Include the next digit (7) from the dividend after 144, then repeat: 1447 / 192

Going ahead to step 7:
192 can be fit into 1447 7 times, resulting in a remainder of 103.
Put 7 as the next digit of the answer. 
Result so far: 43857.0
Deduct 1344 from 1447 and we're left with 103.
Append the next digit (8) from the dividend to 103 and continue with: 1038 / 192

Let's proceed to step 8:
The number 192 fits into 1038 5 times, leaving a remainder of 78.
The next digit of our result is 5. 
Result so far: 438575.0
The remainder is 78 after subtracting 960 from 1038.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 9:
192 can be fit into 780 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 438575.4
If we subtract 768 from 780, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 192 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 438575.4
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
If we divide 1200 by 192, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 438575.406
Subtract 1152 from 1200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
192 can be fit into 480 2 times, resulting in a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 438575.4062
Subtract 384 from 480 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
192 can be fit into 960 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 438575.40625
The remainder is 0 after subtracting 960 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
If we divide 0 by 192, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 438575.40625
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
If we divide 0 by 192, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 438575.40625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 438575.40625 with a remainder of 0.0.
