42399231 ÷ 897 
Let's see how many times 897 fits into 42399231.

Moving on to step 1:
If we divide 4 by 897, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 897

Advancing to step 2:
42 divided by 897 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 897

On to step 3:
If we divide 423 by 897, we get 0 and a remainder of 423.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 423, we get 423.
Append the next digit (9) from the dividend to 423 and continue with: 4239 / 897

Let's proceed to step 4:
897 goes into 4239 4 times with a remainder of 651.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 3588 from 4239 leaves us with 651.
Grab the next digit (9) from the dividend, add it to 651, then carry on: 6519 / 897

Moving on to step 5:
897 can be fit into 6519 7 times, resulting in a remainder of 240.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 6279 from 6519 leaves us with 240.
Bring next digit (2) of the dividend behind the 240 and repeat the process: 2402 / 897

Going ahead to step 6:
897 goes into 2402 2 times with a remainder of 608.
The number 2 becomes the next digit in our result. 
Result so far: 472.0
Deduct 1794 from 2402 and we're left with 608.
Fetch the next digit (3) from the dividend, attach it to 608 and continue: 6083 / 897

Moving on to step 7:
If we divide 6083 by 897, we get 6 and a remainder of 701.
Use 6 as the next digit of our solution. 
Result so far: 4726.0
Deduct 5382 from 6083 and we're left with 701.
Take the next digit (1) from the dividend and append it to 701, then repeat: 7011 / 897

Let's proceed to step 8:
897 goes into 7011 7 times with a remainder of 732.
The number 7 becomes the next digit in our result. 
Result so far: 47267.0
If we subtract 6279 from 7011, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 9:
When dividing 7320 by 897, we get 8 with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 47267.8
Subtracting 7176 from 7320 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 10:
1440 divided by 897 is 1 with a remainder of 543.
Put 1 as the next digit of the answer. 
Result so far: 47267.81
Subtracting 897 from 1440 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Moving on to step 11:
If we divide 5430 by 897, we get 6 and a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 47267.816
The remainder is 48 after subtracting 5382 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
The number 897 fits into 480 0 times, leaving a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 47267.816
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 13:
The number 897 fits into 4800 5 times, leaving a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 47267.81605
If we subtract 4485 from 4800, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 14:
897 goes into 3150 3 times with a remainder of 459.
Record the quotient 3 as the next digit in the result. 
Result so far: 47267.816053
The remainder is 459 after subtracting 2691 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Going ahead to step 15:
897 goes into 4590 5 times with a remainder of 105.
The next digit of our result is 5. 
Result so far: 47267.8160535
If we take 4485 away from 4590, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 16:
897 goes into 1050 1 times with a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 47267.81605351
Subtracting 897 from 1050 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final result is 47267.81605351 with a remainder of 1.53e-07.
