We divide 51373804 by 9
Let's see how many times 9 fits into 51373804.

Moving on to step 1:
When dividing 5 by 9, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 9

Step 2:
9 goes into 51 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 45 from 51, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 9

Moving on to step 3:
The number 9 fits into 63 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Deduct 63 from 63 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 9

Moving on to step 4:
If we divide 7 by 9, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 570.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 9

Advancing to step 5:
9 can be fit into 73 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 5708.0
If we subtract 72 from 73, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

Advancing to step 6:
If we divide 18 by 9, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 57082.0
Deduct 18 from 18 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 9

Going ahead to step 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 570820.0
If we subtract 0 from 0, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 9

Let's proceed to step 8:
The number 9 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 5708200.0
If we subtract 0 from 4, we get 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:
When dividing 40 by 9, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 5708200.4
Deduct 36 from 40 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.

Let's proceed to step 10:
40 divided by 9 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 5708200.44
Deduct 36 from 40 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.

The quotient of the division is 5708200.44, and the remainder is 0.004.
