We look at the division of 393966 by 89 
Let's see how many times 89 fits into 393966.

Moving on to step 1:
3 divided by 89 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 89

Step 2:
The number 89 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 89

Going ahead to step 3:
When dividing 393 by 89, we get 4 with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 356 from 393 and we're left with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 89

On to step 4:
89 goes into 379 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 44.0
If we take 356 away from 379, we end up with 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 89

Advancing to step 5:
236 divided by 89 is 2 with a remainder of 58.
Write down 2 as next digit of the result. 
Result so far: 442.0
If we take 178 away from 236, we end up with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 89

Going ahead to step 6:
If we divide 586 by 89, we get 6 and a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 4426.0
Subtracting 534 from 586 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 7:
89 can be fit into 520 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 4426.5
If we take 445 away from 520, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
The number 89 fits into 750 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 4426.58
If we take 712 away from 750, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
380 divided by 89 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4426.584
If we subtract 356 from 380, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 89, we get 2 and a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 4426.5842
If we take 178 away from 240, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 11:
If we divide 620 by 89, we get 6 and a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 4426.58426
Deduct 534 from 620 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 12:
89 can be fit into 860 9 times, resulting in a remainder of 59.
The next digit of our result is 9. 
Result so far: 4426.584269
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 13:
The number 89 fits into 590 6 times, leaving a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 4426.5842696
If we take 534 away from 590, we end up with 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 14:
The number 89 fits into 560 6 times, leaving a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 4426.58426966
If we subtract 534 from 560, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 4426.58426966, and the remainder is 2.6e-08.
