We look at the division of 34390791 by 237 
Let's see how many times 237 fits into 34390791.

On to step 1:
237 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
Subtracting 0 from 3 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 237

Moving on to step 2:
The number 237 fits into 34 0 times, leaving a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 237

Advancing to step 3:
If we divide 343 by 237, we get 1 and a remainder of 106.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 237 from 343 and we're left with 106.
Bring next digit (9) of the dividend behind the 106 and repeat the process: 1069 / 237

Moving on to step 4:
The number 237 fits into 1069 4 times, leaving a remainder of 121.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 948 away from 1069, we end up with 121.
Include the next digit (0) from the dividend after 121, then repeat: 1210 / 237

Step 5:
237 can be fit into 1210 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 1185 away from 1210, we end up with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 237

Step 6:
237 goes into 257 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1451.0
Deduct 237 from 257 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 237

Moving on to step 7:
The number 237 fits into 209 0 times, leaving a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 14510.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (1) of the dividend behind the 209 and repeat the process: 2091 / 237

Going ahead to step 8:
2091 divided by 237 is 8 with a remainder of 195.
Record the quotient 8 as the next digit in the result. 
Result so far: 145108.0
Deduct 1896 from 2091 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 9:
If we divide 1950 by 237, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 145108.8
Subtract 1896 from 1950 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
If we divide 540 by 237, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 145108.82
If we subtract 474 from 540, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
If we divide 660 by 237, we get 2 and a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 145108.822
If we take 474 away from 660, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Our division results in 145108.822 with a remaining 0.0186.
