We're dividing 64425740 by 397 
We want to divide 64425740 by 397.

Step 1:
397 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 397

Let's proceed to step 2:
The number 397 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 397

On to step 3:
If we divide 644 by 397, we get 1 and a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 397 from 644, we get 247.
Take the next digit (2) from the dividend and append it to 247, then repeat: 2472 / 397

Step 4:
When dividing 2472 by 397, we get 6 with a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2382 from 2472, we get 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 397

Moving on to step 5:
The number 397 fits into 905 2 times, leaving a remainder of 111.
Use 2 as the next digit of our solution. 
Result so far: 162.0
The remainder is 111 after subtracting 794 from 905.
Grab the next digit (7) from the dividend, add it to 111, then carry on: 1117 / 397

Advancing to step 6:
When dividing 1117 by 397, we get 2 with a remainder of 323.
Put 2 as the next digit of the answer. 
Result so far: 1622.0
Subtract 794 from 1117 to get 323.
Bring next digit (4) of the dividend behind the 323 and repeat the process: 3234 / 397

On to step 7:
3234 divided by 397 is 8 with a remainder of 58.
The next digit of our result is 8. 
Result so far: 16228.0
If we take 3176 away from 3234, we end up with 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 397

Moving on to step 8:
397 can be fit into 580 1 times, resulting in a remainder of 183.
The number 1 becomes the next digit in our result. 
Result so far: 162281.0
If we take 397 away from 580, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
1830 divided by 397 is 4 with a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 162281.4
Deduct 1588 from 1830 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 10:
397 can be fit into 2420 6 times, resulting in a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 162281.46
Subtract 2382 from 2420 to get 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 11:
The number 397 fits into 380 0 times, leaving a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 162281.46
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 12:
397 can be fit into 3800 9 times, resulting in a remainder of 227.
Record the quotient 9 as the next digit in the result. 
Result so far: 162281.4609
Deduct 3573 from 3800 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 13:
If we divide 2270 by 397, we get 5 and a remainder of 285.
The next digit of our result is 5. 
Result so far: 162281.46095
If we take 1985 away from 2270, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 14:
When dividing 2850 by 397, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 162281.460957
Subtracting 2779 from 2850 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 15:
When dividing 710 by 397, we get 1 with a remainder of 313.
Record the quotient 1 as the next digit in the result. 
Result so far: 162281.4609571
If we subtract 397 from 710, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 16:
3130 divided by 397 is 7 with a remainder of 351.
The next digit of our result is 7. 
Result so far: 162281.46095717
The remainder is 351 after subtracting 2779 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

After the division, we end up with 162281.46095717 and a remainder of 3.51e-07.
