We're dividing 39200572 by 974 
Let's see how many times 974 fits into 39200572.

Going ahead to step 1:
The number 974 fits into 3 0 times, leaving 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.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 974

Let's proceed to step 2:
974 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 974

Let's proceed to step 3:
392 divided by 974 is 0 with a remainder of 392.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 392 leaves us with 392.
Include the next digit (0) from the dividend after 392, then repeat: 3920 / 974

On to step 4:
If we divide 3920 by 974, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 3896 from 3920 to get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 974

On to step 5:
The number 974 fits into 240 0 times, leaving a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 240 leaves us with 240.
Append the next digit (5) from the dividend to 240 and continue with: 2405 / 974

Advancing to step 6:
When dividing 2405 by 974, we get 2 with a remainder of 457.
Put 2 as the next digit of the answer. 
Result so far: 402.0
The remainder is 457 after subtracting 1948 from 2405.
Fetch the next digit (7) from the dividend, attach it to 457 and continue: 4577 / 974

Step 7:
When dividing 4577 by 974, we get 4 with a remainder of 681.
Put 4 as the next digit of the answer. 
Result so far: 4024.0
If we take 3896 away from 4577, we end up with 681.
Fetch the next digit (2) from the dividend, attach it to 681 and continue: 6812 / 974

Step 8:
6812 divided by 974 is 6 with a remainder of 968.
Put 6 as the next digit of the answer. 
Result so far: 40246.0
If we take 5844 away from 6812, we end up with 968.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9680, and continue the process.

On to step 9:
9680 divided by 974 is 9 with a remainder of 914.
The number 9 becomes the next digit in our result. 
Result so far: 40246.9
If we subtract 8766 from 9680, we get 914.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9140, and continue the process.

Moving on to step 10:
The number 974 fits into 9140 9 times, leaving a remainder of 374.
Write down 9 as next digit of the result. 
Result so far: 40246.99
The remainder is 374 after subtracting 8766 from 9140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The final outcome is 40246.99, with a leftover of 0.374.
