51257318 ÷ 435 
Let's see how many times 435 fits into 51257318.

Let's proceed to step 1:
The number 435 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 435

On to step 2:
435 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 435

Let's proceed to step 3:
435 can be fit into 512 1 times, resulting in a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 435 from 512 leaves us with 77.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 435

Moving on to step 4:
The number 435 fits into 775 1 times, leaving a remainder of 340.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 435 from 775 and we're left with 340.
Grab the next digit (7) from the dividend, add it to 340, then carry on: 3407 / 435

Let's proceed to step 5:
435 goes into 3407 7 times with a remainder of 362.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 3045 away from 3407, we end up with 362.
Append the next digit (3) from the dividend to 362 and continue with: 3623 / 435

Step 6:
When dividing 3623 by 435, we get 8 with a remainder of 143.
Write down 8 as next digit of the result. 
Result so far: 1178.0
The remainder is 143 after subtracting 3480 from 3623.
Take the next digit (1) from the dividend and append it to 143, then repeat: 1431 / 435

Let's proceed to step 7:
If we divide 1431 by 435, we get 3 and a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 11783.0
If we subtract 1305 from 1431, we get 126.
Take the next digit (8) from the dividend and append it to 126, then repeat: 1268 / 435

Let's proceed to step 8:
The number 435 fits into 1268 2 times, leaving a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 117832.0
Deduct 870 from 1268 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 9:
435 can be fit into 3980 9 times, resulting in a remainder of 65.
The next digit of our result is 9. 
Result so far: 117832.9
Deduct 3915 from 3980 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 10:
435 goes into 650 1 times with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 117832.91
If we take 435 away from 650, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 11:
2150 divided by 435 is 4 with a remainder of 410.
Put 4 as the next digit of the answer. 
Result so far: 117832.914
Subtracting 1740 from 2150 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 12:
The number 435 fits into 4100 9 times, leaving a remainder of 185.
Write down 9 as next digit of the result. 
Result so far: 117832.9149
Subtracting 3915 from 4100 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 13:
435 goes into 1850 4 times with a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 117832.91494
If we take 1740 away from 1850, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 14:
The number 435 fits into 1100 2 times, leaving a remainder of 230.
The next digit of our result is 2. 
Result so far: 117832.914942
If we take 870 away from 1100, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 15:
435 goes into 2300 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 117832.9149425
Deduct 2175 from 2300 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 16:
1250 divided by 435 is 2 with a remainder of 380.
The next digit of our result is 2. 
Result so far: 117832.91494252
Subtracting 870 from 1250 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

In conclusion, the division gives 117832.91494252 with a balance of 3.8e-07.
