407570 divided by 84 
We want to figure out the number of times 407570 can be divided by 84.

Advancing to step 1:
If we divide 4 by 84, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 84

Going ahead to step 2:
84 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 84

Step 3:
When dividing 407 by 84, we get 4 with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 336 from 407 leaves us with 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 84

On to step 4:
84 can be fit into 715 8 times, resulting in a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 672 from 715, we get 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 84

Let's proceed to step 5:
The number 84 fits into 437 5 times, leaving a remainder of 17.
The next digit of our result is 5. 
Result so far: 485.0
Deduct 420 from 437 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 84

Step 6:
84 goes into 170 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4852.0
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
84 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4852.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
84 goes into 200 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 4852.02
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
When dividing 320 by 84, we get 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 4852.023
The remainder is 68 after subtracting 252 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
If we divide 680 by 84, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 4852.0238
Subtracting 672 from 680 leaves us 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.

On to step 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 4852.0238
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
84 goes into 800 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 4852.023809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4852.0238095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 84, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 4852.02380952
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 4852.02380952 with a remaining 3.2e-08.
