Let's divide 149581 by 37
We're looking to find how many times 37 goes into 149581.

Going ahead to step 1:
When dividing 1 by 37, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 37

Advancing to step 2:
14 divided by 37 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 37

On to step 3:
If we divide 149 by 37, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 1 after subtracting 148 from 149.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 37

On to step 4:
37 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 37

Going ahead to step 5:
When dividing 158 by 37, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 404.0
Deduct 148 from 158 and we're left with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 37

On to step 6:
When dividing 101 by 37, we get 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 4042.0
Subtracting 74 from 101 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
270 divided by 37 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 4042.7
Subtracting 259 from 270 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
37 goes into 110 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 4042.72
Deduct 74 from 110 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
37 can be fit into 360 9 times, resulting in a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 4042.729
If we subtract 333 from 360, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
When dividing 270 by 37, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 4042.7297
If we subtract 259 from 270, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
37 goes into 110 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 4042.72972
If we subtract 74 from 110, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
If we divide 360 by 37, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 4042.729729
Subtracting 333 from 360 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
37 goes into 270 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 4042.7297297
If we subtract 259 from 270, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
The number 37 fits into 110 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 4042.72972972
If we subtract 74 from 110, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 4042.72972972 and a remainder of 3.6e-08.
