We're dividing 37397903 by 839 
Let's see how many times 839 fits into 37397903.

Moving on to step 1:
839 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 839

Advancing to step 2:
If we divide 37 by 839, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 839

On to step 3:
The number 839 fits into 373 0 times, leaving a remainder of 373.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 373 to get 373.
Fetch the next digit (9) from the dividend, attach it to 373 and continue: 3739 / 839

Moving on to step 4:
839 goes into 3739 4 times with a remainder of 383.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 383 after subtracting 3356 from 3739.
Include the next digit (7) from the dividend after 383, then repeat: 3837 / 839

On to step 5:
If we divide 3837 by 839, we get 4 and a remainder of 481.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 3356 from 3837 and we're left with 481.
Grab the next digit (9) from the dividend, add it to 481, then carry on: 4819 / 839

On to step 6:
839 goes into 4819 5 times with a remainder of 624.
Record the quotient 5 as the next digit in the result. 
Result so far: 445.0
Subtract 4195 from 4819 to get 624.
Append the next digit (0) from the dividend to 624 and continue with: 6240 / 839

On to step 7:
The number 839 fits into 6240 7 times, leaving a remainder of 367.
The next digit of our result is 7. 
Result so far: 4457.0
Deduct 5873 from 6240 and we're left with 367.
Bring next digit (3) of the dividend behind the 367 and repeat the process: 3673 / 839

Going ahead to step 8:
The number 839 fits into 3673 4 times, leaving a remainder of 317.
Write down 4 as next digit of the result. 
Result so far: 44574.0
If we take 3356 away from 3673, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 9:
When dividing 3170 by 839, we get 3 with a remainder of 653.
Use 3 as the next digit of our solution. 
Result so far: 44574.3
Deduct 2517 from 3170 and we're left with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 10:
6530 divided by 839 is 7 with a remainder of 657.
Use 7 as the next digit of our solution. 
Result so far: 44574.37
Subtract 5873 from 6530 to get 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Let's proceed to step 11:
The number 839 fits into 6570 7 times, leaving a remainder of 697.
Record the quotient 7 as the next digit in the result. 
Result so far: 44574.377
If we take 5873 away from 6570, we end up with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

The quotient of the division is 44574.377, and the remainder is 0.0697.
