We're dividing 1469509 by 398 
We want to figure out the number of times 1469509 can be divided by 398.

Advancing to step 1:
The number 398 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 398

Let's proceed to step 2:
The number 398 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 398

On to step 3:
398 goes into 146 0 times with a remainder of 146.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 146 to get 146.
Bring next digit (9) of the dividend behind the 146 and repeat the process: 1469 / 398

Advancing to step 4:
The number 398 fits into 1469 3 times, leaving a remainder of 275.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 275 after subtracting 1194 from 1469.
Take the next digit (5) from the dividend and append it to 275, then repeat: 2755 / 398

Moving on to step 5:
398 can be fit into 2755 6 times, resulting in a remainder of 367.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 2388 from 2755, we get 367.
Take the next digit (0) from the dividend and append it to 367, then repeat: 3670 / 398

Advancing to step 6:
If we divide 3670 by 398, we get 9 and a remainder of 88.
Use 9 as the next digit of our solution. 
Result so far: 369.0
Deduct 3582 from 3670 and we're left with 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 398

Going ahead to step 7:
If we divide 889 by 398, we get 2 and a remainder of 93.
Use 2 as the next digit of our solution. 
Result so far: 3692.0
If we subtract 796 from 889, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 8:
The number 398 fits into 930 2 times, leaving a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 3692.2
The remainder is 134 after subtracting 796 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
1340 divided by 398 is 3 with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 3692.23
Deduct 1194 from 1340 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 10:
The number 398 fits into 1460 3 times, leaving a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 3692.233
If we subtract 1194 from 1460, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

After the division, we end up with 3692.233 and a remainder of 0.0266.
