We look at the division of 126239 by 37 
Let's see how many times 37 fits into 126239.

Let's proceed to step 1:
The number 37 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 37

Step 2:
If we divide 12 by 37, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 37

Step 3:
37 goes into 126 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 111 from 126 and we're left with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 37

Step 4:
If we divide 152 by 37, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 148 away from 152, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 37

Going ahead to step 5:
37 goes into 43 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 341.0
If we subtract 37 from 43, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 37

Step 6:
If we divide 69 by 37, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 3411.0
Deduct 37 from 69 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
320 divided by 37 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 3411.8
Subtract 296 from 320 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
The number 37 fits into 240 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 3411.86
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
180 divided by 37 is 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3411.864
If we take 148 away from 180, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
37 can be fit into 320 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3411.8648
The remainder is 24 after subtracting 296 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
If we divide 240 by 37, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 3411.86486
Subtracting 222 from 240 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
If we divide 180 by 37, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3411.864864
Deduct 148 from 180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
320 divided by 37 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 3411.8648648
The remainder is 24 after subtracting 296 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 37, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 3411.86486486
Deduct 222 from 240 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 3411.86486486, with a leftover of 1.8e-08.
