We look at the division of 421880 by 74 
We're looking to find how many times 74 goes into 421880.

On to step 1:
When dividing 4 by 74, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 74

Moving on to step 2:
74 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 74

Step 3:
The number 74 fits into 421 5 times, leaving a remainder of 51.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 370 from 421 leaves us with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 74

Moving on to step 4:
518 divided by 74 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Deduct 518 from 518 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 74

Moving on to step 5:
The number 74 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 570.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 74

Advancing to step 6:
74 goes into 80 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 5701.0
Subtracting 74 from 80 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 74 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5701.0
If we take 0 away from 60, we end up with 60.
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 8:
The number 74 fits into 600 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5701.08
Subtract 592 from 600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 74, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 5701.081
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
74 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5701.081
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
74 can be fit into 600 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5701.08108
Subtract 592 from 600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 74, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 5701.081081
The remainder is 6 after subtracting 74 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 74 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5701.081081
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
When dividing 600 by 74, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 5701.08108108
Subtract 592 from 600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 5701.08108108, with a leftover of 8e-09.
