291721 ÷ 74 
Our goal is to divide 291721 by 74.

On to step 1:
74 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 74

Let's proceed to step 2:
When dividing 29 by 74, we get 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 74

Going ahead to step 3:
74 goes into 291 3 times with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 222 from 291 leaves us with 69.
Bring next digit (7) of the dividend behind the 69 and repeat the process: 697 / 74

On to step 4:
74 can be fit into 697 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtracting 666 from 697 leaves us with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 74

Let's proceed to step 5:
312 divided by 74 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 394.0
If we subtract 296 from 312, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 74

Advancing to step 6:
If we divide 161 by 74, we get 2 and a remainder of 13.
The next digit of our result is 2. 
Result so far: 3942.0
If we take 148 away from 161, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
74 goes into 130 1 times with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 3942.1
If we subtract 74 from 130, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
The number 74 fits into 560 7 times, leaving a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 3942.17
If we take 518 away from 560, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
The number 74 fits into 420 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 3942.175
Subtracting 370 from 420 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
74 can be fit into 500 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 3942.1756
Subtract 444 from 500 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
74 can be fit into 560 7 times, resulting in a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 3942.17567
If we subtract 518 from 560, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
When dividing 420 by 74, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3942.175675
Subtracting 370 from 420 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
74 goes into 500 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 3942.1756756
Subtract 444 from 500 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
If we divide 560 by 74, we get 7 and a remainder of 42.
The next digit of our result is 7. 
Result so far: 3942.17567567
Deduct 518 from 560 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 3942.17567567, and the remainder is 4.2e-08.
