We look at the division of 667421 by 74 
We want to divide 667421 by 74.

Advancing to step 1:
74 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 74

Going ahead to step 2:
66 divided by 74 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 74

Step 3:
74 goes into 667 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 666 from 667 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 74

On to step 4:
If we divide 14 by 74, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 90.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 74

Advancing to step 5:
The number 74 fits into 142 1 times, leaving a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 901.0
The remainder is 68 after subtracting 74 from 142.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 74

Moving on to step 6:
74 can be fit into 681 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9019.0
If we take 666 away from 681, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
74 can be fit into 150 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 9019.2
Deduct 148 from 150 and we're left with 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 8:
The number 74 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9019.2
If we subtract 0 from 20, we 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.

Moving on to step 9:
74 can be fit into 200 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 9019.202
Subtracting 148 from 200 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 74 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 9019.2027
The remainder is 2 after subtracting 518 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
When dividing 20 by 74, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9019.2027
Deduct 0 from 20 and we're left 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.

Advancing to step 12:
200 divided by 74 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 9019.202702
The remainder is 52 after subtracting 148 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
When dividing 520 by 74, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 9019.2027027
If we subtract 518 from 520, 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.

Moving on to step 14:
74 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9019.2027027
Deduct 0 from 20 and we're left 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.

The final outcome is 9019.2027027, with a leftover of 2e-08.
