We divide 52457403 by 423
We want to divide 52457403 by 423.

Step 1:
The number 423 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 423

Step 2:
If we divide 52 by 423, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 423

Going ahead to step 3:
If we divide 524 by 423, we get 1 and a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 423 from 524, we get 101.
Grab the next digit (5) from the dividend, add it to 101, then carry on: 1015 / 423

Advancing to step 4:
The number 423 fits into 1015 2 times, leaving a remainder of 169.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 169 after subtracting 846 from 1015.
Fetch the next digit (7) from the dividend, attach it to 169 and continue: 1697 / 423

On to step 5:
423 goes into 1697 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 124.0
The remainder is 5 after subtracting 1692 from 1697.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 423

On to step 6:
When dividing 54 by 423, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 1240.0
Deduct 0 from 54 and we're left with 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 423

Going ahead to step 7:
540 divided by 423 is 1 with a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 12401.0
If we subtract 423 from 540, we get 117.
Fetch the next digit (3) from the dividend, attach it to 117 and continue: 1173 / 423

Step 8:
1173 divided by 423 is 2 with a remainder of 327.
Use 2 as the next digit of our solution. 
Result so far: 124012.0
The remainder is 327 after subtracting 846 from 1173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 9:
3270 divided by 423 is 7 with a remainder of 309.
The number 7 becomes the next digit in our result. 
Result so far: 124012.7
Subtracting 2961 from 3270 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 10:
If we divide 3090 by 423, we get 7 and a remainder of 129.
Record the quotient 7 as the next digit in the result. 
Result so far: 124012.77
The remainder is 129 after subtracting 2961 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Our division results in 124012.77 with a remaining 0.129.
