We divide 43434285 by 397
We want to divide 43434285 by 397.

Advancing to step 1:
397 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 397

Going ahead to step 2:
If we divide 43 by 397, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 397

Let's proceed to step 3:
If we divide 434 by 397, we get 1 and a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 397 from 434 and we're left with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 397

On to step 4:
397 can be fit into 373 0 times, resulting in a remainder of 373.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 373, we end up with 373.
Take the next digit (4) from the dividend and append it to 373, then repeat: 3734 / 397

Going ahead to step 5:
3734 divided by 397 is 9 with a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtracting 3573 from 3734 leaves us with 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 397

Let's proceed to step 6:
1612 divided by 397 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1094.0
Deduct 1588 from 1612 and we're left with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 397

Step 7:
248 divided by 397 is 0 with a remainder of 248.
The next digit of our result is 0. 
Result so far: 10940.0
If we subtract 0 from 248, we get 248.
Grab the next digit (5) from the dividend, add it to 248, then carry on: 2485 / 397

Moving on to step 8:
When dividing 2485 by 397, we get 6 with a remainder of 103.
Use 6 as the next digit of our solution. 
Result so far: 109406.0
If we subtract 2382 from 2485, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
The number 397 fits into 1030 2 times, leaving a remainder of 236.
The next digit of our result is 2. 
Result so far: 109406.2
Subtract 794 from 1030 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 10:
397 can be fit into 2360 5 times, resulting in a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 109406.25
If we subtract 1985 from 2360, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 11:
The number 397 fits into 3750 9 times, leaving a remainder of 177.
Put 9 as the next digit of the answer. 
Result so far: 109406.259
If we subtract 3573 from 3750, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 12:
When dividing 1770 by 397, we get 4 with a remainder of 182.
The number 4 becomes the next digit in our result. 
Result so far: 109406.2594
If we take 1588 away from 1770, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 13:
When dividing 1820 by 397, we get 4 with a remainder of 232.
Write down 4 as next digit of the result. 
Result so far: 109406.25944
Subtract 1588 from 1820 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 109406.25944, and the remainder is 0.000232.
