51645151 ÷ 608 
We want to figure out the number of times 51645151 can be divided by 608.

Moving on to step 1:
608 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
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 / 608

Step 2:
The number 608 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (6) from the dividend after 51, then repeat: 516 / 608

Let's proceed to step 3:
608 goes into 516 0 times with a remainder of 516.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Fetch the next digit (4) from the dividend, attach it to 516 and continue: 5164 / 608

Advancing to step 4:
608 can be fit into 5164 8 times, resulting in a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 4864 from 5164 leaves us with 300.
Include the next digit (5) from the dividend after 300, then repeat: 3005 / 608

On to step 5:
608 goes into 3005 4 times with a remainder of 573.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtracting 2432 from 3005 leaves us with 573.
Bring next digit (1) of the dividend behind the 573 and repeat the process: 5731 / 608

Moving on to step 6:
If we divide 5731 by 608, we get 9 and a remainder of 259.
Use 9 as the next digit of our solution. 
Result so far: 849.0
Deduct 5472 from 5731 and we're left with 259.
Take the next digit (5) from the dividend and append it to 259, then repeat: 2595 / 608

On to step 7:
608 goes into 2595 4 times with a remainder of 163.
The next digit of our result is 4. 
Result so far: 8494.0
Deduct 2432 from 2595 and we're left with 163.
Fetch the next digit (1) from the dividend, attach it to 163 and continue: 1631 / 608

Advancing to step 8:
The number 608 fits into 1631 2 times, leaving a remainder of 415.
The next digit of our result is 2. 
Result so far: 84942.0
If we take 1216 away from 1631, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
The number 608 fits into 4150 6 times, leaving a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 84942.6
Subtracting 3648 from 4150 leaves us with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Advancing to step 10:
When dividing 5020 by 608, we get 8 with a remainder of 156.
The next digit of our result is 8. 
Result so far: 84942.68
If we take 4864 away from 5020, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
608 goes into 1560 2 times with a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 84942.682
If we take 1216 away from 1560, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 12:
608 goes into 3440 5 times with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 84942.6825
The remainder is 400 after subtracting 3040 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
608 can be fit into 4000 6 times, resulting in a remainder of 352.
Put 6 as the next digit of the answer. 
Result so far: 84942.68256
If we subtract 3648 from 4000, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 14:
3520 divided by 608 is 5 with a remainder of 480.
Record the quotient 5 as the next digit in the result. 
Result so far: 84942.682565
Subtract 3040 from 3520 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 15:
If we divide 4800 by 608, we get 7 and a remainder of 544.
The next digit of our result is 7. 
Result so far: 84942.6825657
The remainder is 544 after subtracting 4256 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 16:
The number 608 fits into 5440 8 times, leaving a remainder of 576.
The number 8 becomes the next digit in our result. 
Result so far: 84942.68256578
Deduct 4864 from 5440 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final result is 84942.68256578 with a remainder of 5.76e-07.
