We're dividing 37042121 by 839 
We want to figure out the number of times 37042121 can be divided by 839.

Advancing to step 1:
3 divided by 839 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 839

Advancing to step 2:
If we divide 37 by 839, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 839

Advancing to step 3:
839 can be fit into 370 0 times, resulting in a remainder of 370.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 370 after subtracting 0 from 370.
Bring next digit (4) of the dividend behind the 370 and repeat the process: 3704 / 839

Step 4:
839 goes into 3704 4 times with a remainder of 348.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3356 from 3704 and we're left with 348.
Append the next digit (2) from the dividend to 348 and continue with: 3482 / 839

Advancing to step 5:
3482 divided by 839 is 4 with a remainder of 126.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 126 after subtracting 3356 from 3482.
Append the next digit (1) from the dividend to 126 and continue with: 1261 / 839

Step 6:
When dividing 1261 by 839, we get 1 with a remainder of 422.
The next digit of our result is 1. 
Result so far: 441.0
Subtract 839 from 1261 to get 422.
Grab the next digit (2) from the dividend, add it to 422, then carry on: 4222 / 839

Advancing to step 7:
839 can be fit into 4222 5 times, resulting in a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 4415.0
The remainder is 27 after subtracting 4195 from 4222.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 839

Advancing to step 8:
When dividing 271 by 839, we get 0 with a remainder of 271.
Use 0 as the next digit of our solution. 
Result so far: 44150.0
Deduct 0 from 271 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 9:
839 goes into 2710 3 times with a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 44150.3
If we subtract 2517 from 2710, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 10:
839 goes into 1930 2 times with a remainder of 252.
Write down 2 as next digit of the result. 
Result so far: 44150.32
Subtracting 1678 from 1930 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
839 goes into 2520 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 44150.323
If we take 2517 away from 2520, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
839 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 44150.323
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 13:
839 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 44150.323
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 44150.323 with a remainder of 0.0003.
