37919418 ÷ 904 
Our goal is to divide 37919418 by 904.

Step 1:
904 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 904

Going ahead to step 2:
The number 904 fits into 37 0 times, leaving a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 904

Let's proceed to step 3:
904 goes into 379 0 times with a remainder of 379.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 379, we end up with 379.
Grab the next digit (1) from the dividend, add it to 379, then carry on: 3791 / 904

On to step 4:
904 can be fit into 3791 4 times, resulting in a remainder of 175.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 175 after subtracting 3616 from 3791.
Include the next digit (9) from the dividend after 175, then repeat: 1759 / 904

On to step 5:
If we divide 1759 by 904, we get 1 and a remainder of 855.
Write down 1 as next digit of the result. 
Result so far: 41.0
Deduct 904 from 1759 and we're left with 855.
Append the next digit (4) from the dividend to 855 and continue with: 8554 / 904

Going ahead to step 6:
904 can be fit into 8554 9 times, resulting in a remainder of 418.
Use 9 as the next digit of our solution. 
Result so far: 419.0
Deduct 8136 from 8554 and we're left with 418.
Bring next digit (1) of the dividend behind the 418 and repeat the process: 4181 / 904

Let's proceed to step 7:
4181 divided by 904 is 4 with a remainder of 565.
Use 4 as the next digit of our solution. 
Result so far: 4194.0
Deduct 3616 from 4181 and we're left with 565.
Fetch the next digit (8) from the dividend, attach it to 565 and continue: 5658 / 904

Advancing to step 8:
The number 904 fits into 5658 6 times, leaving a remainder of 234.
Write down 6 as next digit of the result. 
Result so far: 41946.0
If we subtract 5424 from 5658, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
904 goes into 2340 2 times with a remainder of 532.
Use 2 as the next digit of our solution. 
Result so far: 41946.2
Subtracting 1808 from 2340 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 10:
5320 divided by 904 is 5 with a remainder of 800.
Write down 5 as next digit of the result. 
Result so far: 41946.25
If we subtract 4520 from 5320, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 11:
The number 904 fits into 8000 8 times, leaving a remainder of 768.
Write down 8 as next digit of the result. 
Result so far: 41946.258
If we take 7232 away from 8000, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

On to step 12:
The number 904 fits into 7680 8 times, leaving a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 41946.2588
Subtract 7232 from 7680 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final result is 41946.2588 with a remainder of 0.00448.
