753387 ÷ 51 
We're looking to find how many times 51 goes into 753387.

On to step 1:
51 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 51

Let's proceed to step 2:
75 divided by 51 is 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 75 leaves us with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 51

Moving on to step 3:
51 can be fit into 243 4 times, resulting in a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 204 from 243 leaves us with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 51

Advancing to step 4:
51 goes into 393 7 times with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 147.0
Subtract 357 from 393 to get 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 51

Step 5:
When dividing 368 by 51, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 1477.0
If we subtract 357 from 368, we get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 51

Let's proceed to step 6:
117 divided by 51 is 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 14772.0
Subtract 102 from 117 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 51, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 14772.2
Subtract 102 from 150 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
If we divide 480 by 51, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 14772.29
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
51 goes into 210 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14772.294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 14772.2941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
90 divided by 51 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 14772.29411
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 14772.29411 with a remaining 3.9e-05.
