51546278 ÷ 758 
Let's see how many times 758 fits into 51546278.

Step 1:
758 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 758

On to step 2:
When dividing 51 by 758, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 758

Going ahead to step 3:
If we divide 515 by 758, we get 0 and a remainder of 515.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Include the next digit (4) from the dividend after 515, then repeat: 5154 / 758

Going ahead to step 4:
5154 divided by 758 is 6 with a remainder of 606.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4548 from 5154 leaves us with 606.
Fetch the next digit (6) from the dividend, attach it to 606 and continue: 6066 / 758

Moving on to step 5:
758 can be fit into 6066 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 68.0
If we subtract 6064 from 6066, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 758

On to step 6:
When dividing 22 by 758, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 680.0
If we take 0 away from 22, we end up with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 758

Advancing to step 7:
If we divide 227 by 758, we get 0 and a remainder of 227.
The next digit of our result is 0. 
Result so far: 6800.0
Subtracting 0 from 227 leaves us with 227.
Bring next digit (8) of the dividend behind the 227 and repeat the process: 2278 / 758

Advancing to step 8:
When dividing 2278 by 758, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 68003.0
Deduct 2274 from 2278 and we're left 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.

Advancing to step 9:
758 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 68003.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
758 can be fit into 400 0 times, resulting in a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 68003.0
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 68003.0 and a remainder of 0.4.
