We look at the division of 3942037 by 936 
We want to figure out the number of times 3942037 can be divided by 936.

Let's proceed to step 1:
When dividing 3 by 936, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 936

On to step 2:
39 divided by 936 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 936

Going ahead to step 3:
936 goes into 394 0 times with a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 394 leaves us with 394.
Fetch the next digit (2) from the dividend, attach it to 394 and continue: 3942 / 936

Step 4:
The number 936 fits into 3942 4 times, leaving a remainder of 198.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3744 away from 3942, we end up with 198.
Take the next digit (0) from the dividend and append it to 198, then repeat: 1980 / 936

Let's proceed to step 5:
1980 divided by 936 is 2 with a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 1872 from 1980, we get 108.
Bring next digit (3) of the dividend behind the 108 and repeat the process: 1083 / 936

Let's proceed to step 6:
If we divide 1083 by 936, we get 1 and a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 421.0
Deduct 936 from 1083 and we're left with 147.
Take the next digit (7) from the dividend and append it to 147, then repeat: 1477 / 936

Let's proceed to step 7:
When dividing 1477 by 936, we get 1 with a remainder of 541.
Put 1 as the next digit of the answer. 
Result so far: 4211.0
Deduct 936 from 1477 and we're left with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Going ahead to step 8:
936 goes into 5410 5 times with a remainder of 730.
The number 5 becomes the next digit in our result. 
Result so far: 4211.5
Subtracting 4680 from 5410 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 9:
The number 936 fits into 7300 7 times, leaving a remainder of 748.
The number 7 becomes the next digit in our result. 
Result so far: 4211.57
If we take 6552 away from 7300, we end up with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Advancing to step 10:
If we divide 7480 by 936, we get 7 and a remainder of 928.
Write down 7 as next digit of the result. 
Result so far: 4211.577
Deduct 6552 from 7480 and we're left with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

After the division, we end up with 4211.577 and a remainder of 0.0928.
