40215 divided by 37 
We want to figure out the number of times 40215 can be divided by 37.

Step 1:
4 divided by 37 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 37

Going ahead to step 2:
37 can be fit into 40 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 37 away from 40, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 37

Advancing to step 3:
If we divide 32 by 37, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 37

Advancing to step 4:
37 can be fit into 321 8 times, resulting in a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 108.0
If we take 296 away from 321, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 37

On to step 5:
37 goes into 255 6 times with a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 1086.0
Subtracting 222 from 255 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 6:
The number 37 fits into 330 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 1086.8
The remainder is 34 after subtracting 296 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
37 can be fit into 340 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1086.89
Subtracting 333 from 340 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 37 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1086.891
The remainder is 33 after subtracting 37 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
When dividing 330 by 37, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 1086.8918
If we take 296 away from 330, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
The number 37 fits into 340 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 1086.89189
The remainder is 7 after subtracting 333 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
37 can be fit into 70 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1086.891891
If we take 37 away from 70, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
37 can be fit into 330 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 1086.8918918
Subtract 296 from 330 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
37 can be fit into 340 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1086.89189189
Deduct 333 from 340 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 1086.89189189 and a remainder of 7e-09.
