39943 divided by 37 
We're looking to find how many times 37 goes into 39943.

Advancing to step 1:
37 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 37

Going ahead to step 2:
37 goes into 39 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 37 from 39 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 37

On to step 3:
37 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 37

Moving on to step 4:
When dividing 294 by 37, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we subtract 259 from 294, we get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 37

Moving on to step 5:
37 goes into 353 9 times with a remainder of 20.
The next digit of our result is 9. 
Result so far: 1079.0
If we take 333 away from 353, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 6:
37 goes into 200 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 1079.5
The remainder is 15 after subtracting 185 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 37, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1079.54
If we subtract 148 from 150, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 37 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 1079.54
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 37 fits into 200 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1079.5405
If we subtract 185 from 200, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
The number 37 fits into 150 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1079.54054
If we take 148 away from 150, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 37, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1079.54054
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
200 divided by 37 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1079.5405405
If we take 185 away from 200, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
37 goes into 150 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1079.54054054
Deduct 148 from 150 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 1079.54054054 with a remaining 2e-09.
