We divide 421605 by 74
We want to figure out the number of times 421605 can be divided by 74.

On to step 1:
74 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 74

Going ahead to step 2:
When dividing 42 by 74, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 74

On to step 3:
The number 74 fits into 421 5 times, leaving a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 370 from 421 to get 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 74

Moving on to step 4:
74 goes into 516 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 444 from 516 to get 72.
Append the next digit (0) from the dividend to 72 and continue with: 720 / 74

Let's proceed to step 5:
74 goes into 720 9 times with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 569.0
The remainder is 54 after subtracting 666 from 720.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 74

Step 6:
545 divided by 74 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 5697.0
Subtract 518 from 545 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
270 divided by 74 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 5697.3
Subtracting 222 from 270 leaves us 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.

Moving on to step 8:
74 can be fit into 480 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 5697.36
The remainder is 36 after subtracting 444 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
74 goes into 360 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 5697.364
If we subtract 296 from 360, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
When dividing 640 by 74, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 5697.3648
Subtract 592 from 640 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 11:
480 divided by 74 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 5697.36486
If we subtract 444 from 480, 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 12:
If we divide 360 by 74, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 5697.364864
Subtracting 296 from 360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 74, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5697.3648648
Subtracting 592 from 640 leaves us 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.

Step 14:
74 can be fit into 480 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 5697.36486486
If we subtract 444 from 480, 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.

Our division results in 5697.36486486 with a remaining 3.6e-08.
