We're dividing 373574 by 51 
Let's see how many times 51 fits into 373574.

Step 1:
51 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 51

On to step 2:
The number 51 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 51

Moving on to step 3:
The number 51 fits into 373 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 357 from 373 leaves us with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 51

Advancing to step 4:
51 can be fit into 165 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 12 after subtracting 153 from 165.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 51

Going ahead to step 5:
51 can be fit into 127 2 times, resulting in a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 732.0
Subtracting 102 from 127 leaves us with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 51

Let's proceed to step 6:
51 goes into 254 4 times with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 7324.0
If we subtract 204 from 254, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 7324.9
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
51 can be fit into 410 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 7324.98
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 51 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7324.98
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
The number 51 fits into 200 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 7324.9803
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
51 goes into 470 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 7324.98039
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
The number 51 fits into 110 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 7324.980392
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
51 can be fit into 80 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 7324.9803921
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
When dividing 290 by 51, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7324.98039215
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 7324.98039215 with a remainder of 3.5e-08.
