Let's divide 143309 by 37
We're looking to find how many times 37 goes into 143309.

On to step 1:
If we divide 1 by 37, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 37

Moving on to step 2:
If we divide 14 by 37, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 37

Advancing to step 3:
When dividing 143 by 37, we get 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 111 from 143 leaves us with 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 37

Step 4:
The number 37 fits into 323 8 times, leaving a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 296 away from 323, we end up with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 37

Let's proceed to step 5:
The number 37 fits into 270 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 387.0
If we subtract 259 from 270, we get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 37

Moving on to step 6:
37 can be fit into 119 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3873.0
Deduct 111 from 119 and we're left 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 7:
80 divided by 37 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 3873.2
Subtract 74 from 80 to 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 8:
The number 37 fits into 60 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 3873.21
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.

Going ahead to step 9:
37 goes into 230 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3873.216
If we subtract 222 from 230, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 37, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 3873.2162
Subtract 74 from 80 to 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.

Let's proceed to step 11:
If we divide 60 by 37, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 3873.21621
Subtract 37 from 60 to 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.

Going ahead to step 12:
37 can be fit into 230 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3873.216216
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.

Step 13:
If we divide 80 by 37, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 3873.2162162
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 14:
When dividing 60 by 37, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 3873.21621621
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.

Our division results in 3873.21621621 with a remaining 2.3e-08.
