742213 ÷ 51 
We're looking to find how many times 51 goes into 742213.

Going ahead to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 51

Step 2:
51 goes into 74 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 74, we get 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 51

Moving on to step 3:
The number 51 fits into 232 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 28 after subtracting 204 from 232.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 51

Let's proceed to step 4:
The number 51 fits into 282 5 times, leaving a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we take 255 away from 282, we end up with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 51

Going ahead to step 5:
271 divided by 51 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1455.0
The remainder is 16 after subtracting 255 from 271.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 51

Let's proceed to step 6:
If we divide 163 by 51, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 14553.0
The remainder is 10 after subtracting 153 from 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 51 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 14553.1
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 14553.19
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
51 goes into 310 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 14553.196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 51 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 14553.196
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 51, we get 7 and a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 14553.19607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
51 can be fit into 430 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 14553.196078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 14553.1960784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 51 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 14553.19607843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 14553.19607843, and the remainder is 7e-09.
