343991 ÷ 37 
We're looking to find how many times 37 goes into 343991.

Advancing to step 1:
The number 37 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 37

Step 2:
When dividing 34 by 37, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 37

On to step 3:
When dividing 343 by 37, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 333 away from 343, we end up with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 37

Moving on to step 4:
37 goes into 109 2 times with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtract 74 from 109 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 37

Moving on to step 5:
37 can be fit into 359 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 929.0
If we take 333 away from 359, we end up with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 37

Moving on to step 6:
37 goes into 261 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 9297.0
If we take 259 away from 261, 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.

Advancing to step 7:
37 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9297.0
Subtracting 0 from 20 leaves us 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.

Going ahead to step 8:
37 goes into 200 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 9297.05
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.

Moving on to step 9:
37 goes into 150 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 9297.054
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.

Going ahead to step 10:
37 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9297.054
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.

Let's proceed to step 11:
The number 37 fits into 200 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9297.05405
Subtracting 185 from 200 leaves us 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.

Step 12:
The number 37 fits into 150 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 9297.054054
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.

Let's proceed to step 13:
If we divide 20 by 37, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 9297.054054
If we take 0 away from 20, 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.

Advancing to step 14:
The number 37 fits into 200 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 9297.05405405
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.

The quotient of the division is 9297.05405405, and the remainder is 1.5e-08.
