65346431 ÷ 397 
We want to figure out the number of times 65346431 can be divided by 397.

Let's proceed to step 1:
397 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 397

Advancing to step 2:
397 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 397

On to step 3:
When dividing 653 by 397, we get 1 with a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 397 away from 653, we end up with 256.
Include the next digit (4) from the dividend after 256, then repeat: 2564 / 397

Advancing to step 4:
2564 divided by 397 is 6 with a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 2382 away from 2564, we end up with 182.
Grab the next digit (6) from the dividend, add it to 182, then carry on: 1826 / 397

Step 5:
If we divide 1826 by 397, we get 4 and a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
If we subtract 1588 from 1826, we get 238.
Take the next digit (4) from the dividend and append it to 238, then repeat: 2384 / 397

Moving on to step 6:
397 goes into 2384 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1646.0
Subtracting 2382 from 2384 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 397

Going ahead to step 7:
23 divided by 397 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 16460.0
Deduct 0 from 23 and we're left with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 397

Going ahead to step 8:
The number 397 fits into 231 0 times, leaving a remainder of 231.
Put 0 as the next digit of the answer. 
Result so far: 164600.0
The remainder is 231 after subtracting 0 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 9:
2310 divided by 397 is 5 with a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 164600.5
Subtracting 1985 from 2310 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 10:
When dividing 3250 by 397, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 164600.58
The remainder is 74 after subtracting 3176 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
If we divide 740 by 397, we get 1 and a remainder of 343.
The next digit of our result is 1. 
Result so far: 164600.581
Deduct 397 from 740 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 12:
When dividing 3430 by 397, we get 8 with a remainder of 254.
Record the quotient 8 as the next digit in the result. 
Result so far: 164600.5818
If we take 3176 away from 3430, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 13:
When dividing 2540 by 397, we get 6 with a remainder of 158.
The next digit of our result is 6. 
Result so far: 164600.58186
Subtracting 2382 from 2540 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 14:
397 can be fit into 1580 3 times, resulting in a remainder of 389.
Put 3 as the next digit of the answer. 
Result so far: 164600.581863
Subtract 1191 from 1580 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Going ahead to step 15:
The number 397 fits into 3890 9 times, leaving a remainder of 317.
The next digit of our result is 9. 
Result so far: 164600.5818639
Subtracting 3573 from 3890 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 16:
3170 divided by 397 is 7 with a remainder of 391.
Put 7 as the next digit of the answer. 
Result so far: 164600.58186397
Deduct 2779 from 3170 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

After the division, we end up with 164600.58186397 and a remainder of 3.91e-07.
