We're dividing 123578 by 74 
Let's see how many times 74 fits into 123578.

Advancing to step 1:
If we divide 1 by 74, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 74

Step 2:
When dividing 12 by 74, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 74

On to step 3:
The number 74 fits into 123 1 times, leaving a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 74 away from 123, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 74

Advancing to step 4:
When dividing 495 by 74, we get 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 444 from 495 leaves us with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 74

Step 5:
74 can be fit into 517 6 times, resulting in a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Deduct 444 from 517 and we're left with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 74

Moving on to step 6:
When dividing 738 by 74, we get 9 with a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 1669.0
The remainder is 72 after subtracting 666 from 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
74 can be fit into 720 9 times, resulting in a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 1669.9
Subtracting 666 from 720 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 8:
74 can be fit into 540 7 times, resulting in a remainder of 22.
The next digit of our result is 7. 
Result so far: 1669.97
If we subtract 518 from 540, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
74 goes into 220 2 times with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 1669.972
Subtract 148 from 220 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
74 goes into 720 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 1669.9729
Subtracting 666 from 720 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
540 divided by 74 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 1669.97297
If we subtract 518 from 540, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 74 fits into 220 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 1669.972972
If we subtract 148 from 220, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
When dividing 720 by 74, we get 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 1669.9729729
Subtracting 666 from 720 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
When dividing 540 by 74, we get 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 1669.97297297
Subtracting 518 from 540 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 1669.97297297, and the remainder is 2.2e-08.
