We look at the division of 51254790 by 436 
Let's see how many times 436 fits into 51254790.

Advancing to step 1:
If we divide 5 by 436, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 436

Moving on to step 2:
When dividing 51 by 436, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 436

Moving on to step 3:
The number 436 fits into 512 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 436 away from 512, we end up with 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 436

Let's proceed to step 4:
When dividing 765 by 436, we get 1 with a remainder of 329.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 436 from 765, we get 329.
Fetch the next digit (4) from the dividend, attach it to 329 and continue: 3294 / 436

Advancing to step 5:
The number 436 fits into 3294 7 times, leaving a remainder of 242.
Put 7 as the next digit of the answer. 
Result so far: 117.0
The remainder is 242 after subtracting 3052 from 3294.
Fetch the next digit (7) from the dividend, attach it to 242 and continue: 2427 / 436

On to step 6:
436 can be fit into 2427 5 times, resulting in a remainder of 247.
Write down 5 as next digit of the result. 
Result so far: 1175.0
If we subtract 2180 from 2427, we get 247.
Grab the next digit (9) from the dividend, add it to 247, then carry on: 2479 / 436

Step 7:
If we divide 2479 by 436, we get 5 and a remainder of 299.
Record the quotient 5 as the next digit in the result. 
Result so far: 11755.0
Subtracting 2180 from 2479 leaves us with 299.
Bring next digit (0) of the dividend behind the 299 and repeat the process: 2990 / 436

Advancing to step 8:
If we divide 2990 by 436, we get 6 and a remainder of 374.
Record the quotient 6 as the next digit in the result. 
Result so far: 117556.0
Subtracting 2616 from 2990 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 9:
The number 436 fits into 3740 8 times, leaving a remainder of 252.
Record the quotient 8 as the next digit in the result. 
Result so far: 117556.8
Subtract 3488 from 3740 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 10:
The number 436 fits into 2520 5 times, leaving a remainder of 340.
The next digit of our result is 5. 
Result so far: 117556.85
The remainder is 340 after subtracting 2180 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
436 goes into 3400 7 times with a remainder of 348.
Write down 7 as next digit of the result. 
Result so far: 117556.857
Subtract 3052 from 3400 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 12:
436 goes into 3480 7 times with a remainder of 428.
Use 7 as the next digit of our solution. 
Result so far: 117556.8577
Subtracting 3052 from 3480 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

After the division, we end up with 117556.8577 and a remainder of 0.00428.
