We're dividing 425445 by 84 
We want to figure out the number of times 425445 can be divided by 84.

Step 1:
4 divided by 84 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 84

On to step 2:
When dividing 42 by 84, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 84

Step 3:
When dividing 425 by 84, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 420 from 425 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 84

Let's proceed to step 4:
84 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 84

On to step 5:
When dividing 544 by 84, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 506.0
Subtract 504 from 544 to get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 84

Moving on to step 6:
The number 84 fits into 405 4 times, leaving a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 5064.0
Subtract 336 from 405 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
If we divide 690 by 84, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 5064.8
Deduct 672 from 690 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
If we divide 180 by 84, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 5064.82
Subtract 168 from 180 to 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.

Moving on to step 9:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 5064.821
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 5064.8214
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
If we divide 240 by 84, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 5064.82142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
720 divided by 84 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 5064.821428
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
84 goes into 480 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 5064.8214285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
84 goes into 600 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 5064.82142857
Subtract 588 from 600 to 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.

The quotient of the division is 5064.82142857, and the remainder is 1.2e-08.
