We're dividing 863440 by 37 
Let's see how many times 37 fits into 863440.

Step 1:
37 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 37

Going ahead to step 2:
The number 37 fits into 86 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 74 from 86 leaves us with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 37

Step 3:
If we divide 123 by 37, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 23.0
If we take 111 away from 123, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 37

On to step 4:
37 can be fit into 124 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
If we take 111 away from 124, we end up with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 37

Step 5:
37 can be fit into 134 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 2333.0
If we take 111 away from 134, we end up with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 37

Step 6:
The number 37 fits into 230 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 23336.0
The remainder is 8 after subtracting 222 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 37 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 23336.2
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
The number 37 fits into 60 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 23336.21
Subtracting 37 from 60 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
The number 37 fits into 230 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 23336.216
If we take 222 away from 230, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 37, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 23336.2162
If we subtract 74 from 80, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
37 can be fit into 60 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 23336.21621
If we subtract 37 from 60, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
37 goes into 230 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 23336.216216
Subtracting 222 from 230 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
37 can be fit into 80 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 23336.2162162
Subtracting 74 from 80 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
37 can be fit into 60 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 23336.21621621
Deduct 37 from 60 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 23336.21621621 with a remainder of 2.3e-08.
