We divide 3421253 by 128
We want to divide 3421253 by 128.

Step 1:
3 divided by 128 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 128

Let's proceed to step 2:
34 divided by 128 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 128

Let's proceed to step 3:
128 can be fit into 342 2 times, resulting in a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 256 from 342, we get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 128

On to step 4:
128 can be fit into 861 6 times, resulting in a remainder of 93.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 768 from 861 to get 93.
Include the next digit (2) from the dividend after 93, then repeat: 932 / 128

On to step 5:
The number 128 fits into 932 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
The remainder is 36 after subtracting 896 from 932.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 128

Moving on to step 6:
128 can be fit into 365 2 times, resulting in a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 2672.0
Subtracting 256 from 365 leaves us with 109.
Bring next digit (3) of the dividend behind the 109 and repeat the process: 1093 / 128

On to step 7:
128 goes into 1093 8 times with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 26728.0
Subtracting 1024 from 1093 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 8:
The number 128 fits into 690 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 26728.5
If we take 640 away from 690, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
500 divided by 128 is 3 with a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 26728.53
Subtract 384 from 500 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 10:
When dividing 1160 by 128, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 26728.539
If we take 1152 away from 1160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
128 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 26728.539
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 128, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 26728.53906
Subtract 768 from 800 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
The number 128 fits into 320 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 26728.539062
Subtracting 256 from 320 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
128 goes into 640 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 26728.5390625
Subtract 640 from 640 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.

Step 15:
If we divide 0 by 128, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26728.5390625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 26728.5390625 with a balance of 0.0.
