We divide 51498593 by 128
We want to divide 51498593 by 128.

Going ahead to step 1:
The number 128 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 128

Step 2:
If we divide 51 by 128, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 128

Let's proceed to step 3:
When dividing 514 by 128, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 4.0
If we take 512 away from 514, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 128

Step 4:
128 can be fit into 29 0 times, resulting in a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtracting 0 from 29 leaves us with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 128

Step 5:
The number 128 fits into 298 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 402.0
Deduct 256 from 298 and we're left with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 128

Let's proceed to step 6:
If we divide 425 by 128, we get 3 and a remainder of 41.
The next digit of our result is 3. 
Result so far: 4023.0
Subtract 384 from 425 to get 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 128

Advancing to step 7:
419 divided by 128 is 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 40233.0
If we take 384 away from 419, we end up with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 128

Going ahead to step 8:
128 goes into 353 2 times with a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 402332.0
If we subtract 256 from 353, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
If we divide 970 by 128, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 402332.7
Subtract 896 from 970 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
128 can be fit into 740 5 times, resulting in a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 402332.75
If we subtract 640 from 740, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
The number 128 fits into 1000 7 times, leaving a remainder of 104.
The next digit of our result is 7. 
Result so far: 402332.757
If we subtract 896 from 1000, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
1040 divided by 128 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 402332.7578
Subtract 1024 from 1040 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
If we divide 160 by 128, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 402332.75781
If we take 128 away from 160, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
128 can be fit into 320 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 402332.757812
Subtract 256 from 320 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
If we divide 640 by 128, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 402332.7578125
If we subtract 640 from 640, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
If we divide 0 by 128, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 402332.7578125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 402332.7578125, with a leftover of 0.0.
