We look at the division of 70669336 by 512 
We're looking to find how many times 512 goes into 70669336.

Going ahead to step 1:
The number 512 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 512

Let's proceed to step 2:
512 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (6) from the dividend after 70, then repeat: 706 / 512

Step 3:
The number 512 fits into 706 1 times, leaving a remainder of 194.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 512 from 706 and we're left with 194.
Fetch the next digit (6) from the dividend, attach it to 194 and continue: 1946 / 512

Step 4:
1946 divided by 512 is 3 with a remainder of 410.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 410 after subtracting 1536 from 1946.
Bring next digit (9) of the dividend behind the 410 and repeat the process: 4109 / 512

Advancing to step 5:
If we divide 4109 by 512, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
Subtract 4096 from 4109 to get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 512

Moving on to step 6:
The number 512 fits into 133 0 times, leaving a remainder of 133.
Record the quotient 0 as the next digit in the result. 
Result so far: 1380.0
The remainder is 133 after subtracting 0 from 133.
Grab the next digit (3) from the dividend, add it to 133, then carry on: 1333 / 512

Step 7:
512 can be fit into 1333 2 times, resulting in a remainder of 309.
The next digit of our result is 2. 
Result so far: 13802.0
If we take 1024 away from 1333, we end up with 309.
Grab the next digit (6) from the dividend, add it to 309, then carry on: 3096 / 512

Moving on to step 8:
If we divide 3096 by 512, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 138026.0
If we take 3072 away from 3096, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 512, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 138026.0
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
When dividing 2400 by 512, we get 4 with a remainder of 352.
Use 4 as the next digit of our solution. 
Result so far: 138026.04
Deduct 2048 from 2400 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 11:
512 goes into 3520 6 times with a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 138026.046
Deduct 3072 from 3520 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 12:
When dividing 4480 by 512, we get 8 with a remainder of 384.
Write down 8 as next digit of the result. 
Result so far: 138026.0468
If we take 4096 away from 4480, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 13:
The number 512 fits into 3840 7 times, leaving a remainder of 256.
Write down 7 as next digit of the result. 
Result so far: 138026.04687
The remainder is 256 after subtracting 3584 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 14:
The number 512 fits into 2560 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 138026.046875
If we take 2560 away from 2560, 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.

Moving on to step 15:
512 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 138026.046875
If we subtract 0 from 0, 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.

Step 16:
512 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 138026.046875
Deduct 0 from 0 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.

The final outcome is 138026.046875, with a leftover of 0.0.
