Let's divide 43470150 by 397
Our goal is to divide 43470150 by 397.

On to step 1:
If we divide 4 by 397, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 397

Step 2:
The number 397 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 397

Step 3:
434 divided by 397 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 397 from 434 and we're left with 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 397

On to step 4:
397 goes into 377 0 times with a remainder of 377.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 377, we end up with 377.
Fetch the next digit (0) from the dividend, attach it to 377 and continue: 3770 / 397

On to step 5:
397 can be fit into 3770 9 times, resulting in a remainder of 197.
The next digit of our result is 9. 
Result so far: 109.0
If we subtract 3573 from 3770, we get 197.
Take the next digit (1) from the dividend and append it to 197, then repeat: 1971 / 397

Moving on to step 6:
The number 397 fits into 1971 4 times, leaving a remainder of 383.
Use 4 as the next digit of our solution. 
Result so far: 1094.0
If we subtract 1588 from 1971, we get 383.
Include the next digit (5) from the dividend after 383, then repeat: 3835 / 397

On to step 7:
397 can be fit into 3835 9 times, resulting in a remainder of 262.
Record the quotient 9 as the next digit in the result. 
Result so far: 10949.0
The remainder is 262 after subtracting 3573 from 3835.
Include the next digit (0) from the dividend after 262, then repeat: 2620 / 397

Moving on to step 8:
When dividing 2620 by 397, we get 6 with a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 109496.0
Subtracting 2382 from 2620 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 9:
397 goes into 2380 5 times with a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 109496.5
Deduct 1985 from 2380 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 10:
3950 divided by 397 is 9 with a remainder of 377.
Write down 9 as next digit of the result. 
Result so far: 109496.59
The remainder is 377 after subtracting 3573 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Step 11:
397 can be fit into 3770 9 times, resulting in a remainder of 197.
The number 9 becomes the next digit in our result. 
Result so far: 109496.599
If we take 3573 away from 3770, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Our division results in 109496.599 with a remaining 0.0197.
