375412 ÷ 51 
We want to figure out the number of times 375412 can be divided by 51.

Going ahead to step 1:
51 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 51

Let's proceed to step 2:
51 goes into 37 0 times with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 51

Step 3:
51 can be fit into 375 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 357 from 375 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 51

Going ahead to step 4:
51 goes into 184 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 153 from 184 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 51

Let's proceed to step 5:
51 goes into 311 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 736.0
The remainder is 5 after subtracting 306 from 311.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 51

Moving on to step 6:
The number 51 fits into 52 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 7361.0
If we take 51 away from 52, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
51 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7361.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 51, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 7361.01
If we subtract 51 from 100, we 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.

Moving on to step 9:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 7361.019
Subtract 459 from 490 to get 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 10:
51 goes into 310 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7361.0196
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
40 divided by 51 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7361.0196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
51 goes into 400 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 7361.019607
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
If we divide 430 by 51, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 7361.0196078
Subtract 408 from 430 to get 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 14:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7361.01960784
If we subtract 204 from 220, we 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.

Our division results in 7361.01960784 with a remaining 1.6e-08.
