Let's divide 398961 by 74
We want to divide 398961 by 74.

Going ahead to step 1:
If we divide 3 by 74, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 74

On to step 2:
If we divide 39 by 74, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 74

Let's proceed to step 3:
74 goes into 398 5 times with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 370 from 398, we get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 74

Let's proceed to step 4:
If we divide 289 by 74, we get 3 and a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 222 from 289 and we're left with 67.
Fetch the next digit (6) from the dividend, attach it to 67 and continue: 676 / 74

On to step 5:
74 can be fit into 676 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 539.0
Subtracting 666 from 676 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 74

Advancing to step 6:
74 goes into 101 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 5391.0
If we subtract 74 from 101, we 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.

Step 7:
If we divide 270 by 74, we get 3 and a remainder of 48.
The next digit of our result is 3. 
Result so far: 5391.3
If we take 222 away from 270, we end up 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:
When dividing 480 by 74, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 5391.36
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.

On to step 9:
74 goes into 360 4 times with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 5391.364
If we take 296 away from 360, we end up 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.

Let's proceed to step 10:
The number 74 fits into 640 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 5391.3648
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.

Moving on to step 11:
The number 74 fits into 480 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 5391.36486
Subtract 444 from 480 to 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.

Going ahead to step 12:
When dividing 360 by 74, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 5391.364864
Subtract 296 from 360 to 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 13:
If we divide 640 by 74, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5391.3648648
If we subtract 592 from 640, we 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.

Moving on to step 14:
When dividing 480 by 74, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 5391.36486486
Deduct 444 from 480 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 5391.36486486 with a remainder of 3.6e-08.
