We're dividing 51591275 by 361 
Our goal is to divide 51591275 by 361.

Let's proceed to step 1:
361 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 361

On to step 2:
The number 361 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 361

Going ahead to step 3:
361 can be fit into 515 1 times, resulting in a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 154 after subtracting 361 from 515.
Take the next digit (9) from the dividend and append it to 154, then repeat: 1549 / 361

On to step 4:
If we divide 1549 by 361, we get 4 and a remainder of 105.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 1444 from 1549 to get 105.
Take the next digit (1) from the dividend and append it to 105, then repeat: 1051 / 361

Advancing to step 5:
1051 divided by 361 is 2 with a remainder of 329.
Put 2 as the next digit of the answer. 
Result so far: 142.0
The remainder is 329 after subtracting 722 from 1051.
Take the next digit (2) from the dividend and append it to 329, then repeat: 3292 / 361

On to step 6:
When dividing 3292 by 361, we get 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 1429.0
Subtract 3249 from 3292 to get 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 361

Moving on to step 7:
When dividing 437 by 361, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 14291.0
If we take 361 away from 437, we end up with 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 361

Let's proceed to step 8:
361 goes into 765 2 times with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 142912.0
If we subtract 722 from 765, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
361 goes into 430 1 times with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 142912.1
The remainder is 69 after subtracting 361 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
When dividing 690 by 361, we get 1 with a remainder of 329.
Record the quotient 1 as the next digit in the result. 
Result so far: 142912.11
If we take 361 away from 690, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

The quotient of the division is 142912.11, and the remainder is 0.329.
