We're dividing 42122030 by 951 
Our goal is to divide 42122030 by 951.

Step 1:
When dividing 4 by 951, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 951

Let's proceed to step 2:
The number 951 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 951

Going ahead to step 3:
The number 951 fits into 421 0 times, leaving a remainder of 421.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 421, we end up with 421.
Bring next digit (2) of the dividend behind the 421 and repeat the process: 4212 / 951

Going ahead to step 4:
The number 951 fits into 4212 4 times, leaving a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3804 from 4212 and we're left with 408.
Include the next digit (2) from the dividend after 408, then repeat: 4082 / 951

Advancing to step 5:
951 can be fit into 4082 4 times, resulting in a remainder of 278.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 278 after subtracting 3804 from 4082.
Bring next digit (0) of the dividend behind the 278 and repeat the process: 2780 / 951

Step 6:
The number 951 fits into 2780 2 times, leaving a remainder of 878.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
If we take 1902 away from 2780, we end up with 878.
Append the next digit (3) from the dividend to 878 and continue with: 8783 / 951

Going ahead to step 7:
951 can be fit into 8783 9 times, resulting in a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 4429.0
If we subtract 8559 from 8783, we get 224.
Fetch the next digit (0) from the dividend, attach it to 224 and continue: 2240 / 951

On to step 8:
2240 divided by 951 is 2 with a remainder of 338.
Put 2 as the next digit of the answer. 
Result so far: 44292.0
If we take 1902 away from 2240, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
When dividing 3380 by 951, we get 3 with a remainder of 527.
Record the quotient 3 as the next digit in the result. 
Result so far: 44292.3
Subtracting 2853 from 3380 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Step 10:
951 can be fit into 5270 5 times, resulting in a remainder of 515.
Record the quotient 5 as the next digit in the result. 
Result so far: 44292.35
If we take 4755 away from 5270, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 11:
The number 951 fits into 5150 5 times, leaving a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 44292.355
The remainder is 395 after subtracting 4755 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

After the division, we end up with 44292.355 and a remainder of 0.0395.
