Let's divide 65440722 by 398
Our goal is to divide 65440722 by 398.

Let's proceed to step 1:
When dividing 6 by 398, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 398

Step 2:
The number 398 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 398

On to step 3:
654 divided by 398 is 1 with a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 256 after subtracting 398 from 654.
Bring next digit (4) of the dividend behind the 256 and repeat the process: 2564 / 398

On to step 4:
The number 398 fits into 2564 6 times, leaving a remainder of 176.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 2388 from 2564 leaves us with 176.
Append the next digit (0) from the dividend to 176 and continue with: 1760 / 398

Advancing to step 5:
The number 398 fits into 1760 4 times, leaving a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtracting 1592 from 1760 leaves us with 168.
Grab the next digit (7) from the dividend, add it to 168, then carry on: 1687 / 398

Moving on to step 6:
398 goes into 1687 4 times with a remainder of 95.
Record the quotient 4 as the next digit in the result. 
Result so far: 1644.0
Deduct 1592 from 1687 and we're left with 95.
Grab the next digit (2) from the dividend, add it to 95, then carry on: 952 / 398

Let's proceed to step 7:
398 can be fit into 952 2 times, resulting in a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 16442.0
The remainder is 156 after subtracting 796 from 952.
Take the next digit (2) from the dividend and append it to 156, then repeat: 1562 / 398

Moving on to step 8:
1562 divided by 398 is 3 with a remainder of 368.
Use 3 as the next digit of our solution. 
Result so far: 164423.0
If we subtract 1194 from 1562, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 9:
398 goes into 3680 9 times with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 164423.9
Deduct 3582 from 3680 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
398 goes into 980 2 times with a remainder of 184.
The next digit of our result is 2. 
Result so far: 164423.92
If we take 796 away from 980, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 11:
If we divide 1840 by 398, we get 4 and a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 164423.924
The remainder is 248 after subtracting 1592 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 12:
When dividing 2480 by 398, we get 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 164423.9246
Deduct 2388 from 2480 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 13:
398 can be fit into 920 2 times, resulting in a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 164423.92462
Subtracting 796 from 920 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
When dividing 1240 by 398, we get 3 with a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 164423.924623
Subtract 1194 from 1240 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
The number 398 fits into 460 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 164423.9246231
The remainder is 62 after subtracting 398 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 16:
When dividing 620 by 398, we get 1 with a remainder of 222.
Put 1 as the next digit of the answer. 
Result so far: 164423.92462311
If we take 398 away from 620, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

In conclusion, the division gives 164423.92462311 with a balance of 2.22e-07.
