We divide 70687891 by 128
We're looking to find how many times 128 goes into 70687891.

Moving on to step 1:
128 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 128

Moving on to step 2:
128 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 128

Advancing to step 3:
The number 128 fits into 706 5 times, leaving a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 640 from 706 leaves us with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 128

Advancing to step 4:
668 divided by 128 is 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 640 from 668 and we're left with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 128

Step 5:
The number 128 fits into 287 2 times, leaving a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 552.0
If we take 256 away from 287, we end up with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 128

On to step 6:
If we divide 318 by 128, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 5522.0
If we take 256 away from 318, we end up with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 128

Going ahead to step 7:
128 goes into 629 4 times with a remainder of 117.
Record the quotient 4 as the next digit in the result. 
Result so far: 55224.0
Deduct 512 from 629 and we're left with 117.
Append the next digit (1) from the dividend to 117 and continue with: 1171 / 128

Moving on to step 8:
The number 128 fits into 1171 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 552249.0
If we take 1152 away from 1171, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
If we divide 190 by 128, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 552249.1
If we subtract 128 from 190, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
128 can be fit into 620 4 times, resulting in a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 552249.14
If we subtract 512 from 620, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
128 can be fit into 1080 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 552249.148
The remainder is 56 after subtracting 1024 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
When dividing 560 by 128, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 552249.1484
Deduct 512 from 560 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
480 divided by 128 is 3 with a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 552249.14843
If we subtract 384 from 480, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 14:
960 divided by 128 is 7 with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 552249.148437
Subtracting 896 from 960 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.

On to 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: 552249.1484375
Deduct 640 from 640 and we're left 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.

On to step 16:
128 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 552249.1484375
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.

Our division results in 552249.1484375 with a remaining 0.0.
