We're dividing 51557137 by 23 
We want to figure out the number of times 51557137 can be divided by 23.

Step 1:
23 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 23

Step 2:
51 divided by 23 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 46 from 51 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 23

Let's proceed to step 3:
23 goes into 55 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 46 from 55 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 23

Let's proceed to step 4:
23 can be fit into 95 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 224.0
If we subtract 92 from 95, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 23

Moving on to step 5:
23 can be fit into 37 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 2241.0
If we take 23 away from 37, we end up with 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 23

Moving on to step 6:
141 divided by 23 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 22416.0
The remainder is 3 after subtracting 138 from 141.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 23

On to step 7:
23 can be fit into 33 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 224161.0
Subtracting 23 from 33 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 23

Moving on to step 8:
107 divided by 23 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 2241614.0
Subtract 92 from 107 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
If we divide 150 by 23, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 2241614.6
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 2241614.65
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
If we divide 50 by 23, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2241614.652
Deduct 46 from 50 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 12:
40 divided by 23 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 2241614.6521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2241614.65217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
90 divided by 23 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 2241614.652173
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 15:
When dividing 210 by 23, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 2241614.6521739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 16:
When dividing 30 by 23, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 2241614.65217391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 2241614.65217391 and a remainder of 7e-09.
