We're dividing 51340423 by 880 
We want to divide 51340423 by 880.

On to step 1:
When dividing 5 by 880, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 880

Advancing to step 2:
When dividing 51 by 880, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 880

On to step 3:
When dividing 513 by 880, we get 0 with a remainder of 513.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 513 after subtracting 0 from 513.
Append the next digit (4) from the dividend to 513 and continue with: 5134 / 880

Let's proceed to step 4:
880 can be fit into 5134 5 times, resulting in a remainder of 734.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4400 from 5134, we get 734.
Append the next digit (0) from the dividend to 734 and continue with: 7340 / 880

Let's proceed to step 5:
880 goes into 7340 8 times with a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 7040 from 7340 and we're left with 300.
Bring next digit (4) of the dividend behind the 300 and repeat the process: 3004 / 880

Moving on to step 6:
When dividing 3004 by 880, we get 3 with a remainder of 364.
Record the quotient 3 as the next digit in the result. 
Result so far: 583.0
Subtracting 2640 from 3004 leaves us with 364.
Include the next digit (2) from the dividend after 364, then repeat: 3642 / 880

On to step 7:
880 can be fit into 3642 4 times, resulting in a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 5834.0
If we subtract 3520 from 3642, we get 122.
Include the next digit (3) from the dividend after 122, then repeat: 1223 / 880

Moving on to step 8:
1223 divided by 880 is 1 with a remainder of 343.
Use 1 as the next digit of our solution. 
Result so far: 58341.0
If we subtract 880 from 1223, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 9:
3430 divided by 880 is 3 with a remainder of 790.
Put 3 as the next digit of the answer. 
Result so far: 58341.3
If we subtract 2640 from 3430, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 10:
7900 divided by 880 is 8 with a remainder of 860.
The number 8 becomes the next digit in our result. 
Result so far: 58341.38
If we subtract 7040 from 7900, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Let's proceed to step 11:
880 goes into 8600 9 times with a remainder of 680.
Record the quotient 9 as the next digit in the result. 
Result so far: 58341.389
Subtracting 7920 from 8600 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 12:
6800 divided by 880 is 7 with a remainder of 640.
The next digit of our result is 7. 
Result so far: 58341.3897
Deduct 6160 from 6800 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
The number 880 fits into 6400 7 times, leaving a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 58341.38977
If we subtract 6160 from 6400, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 58341.38977 with a remainder of 0.00024.
