We're dividing 66971146 by 256 
We want to figure out the number of times 66971146 can be divided by 256.

Advancing to step 1:
6 divided by 256 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 256

Let's proceed to step 2:
256 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 256

Going ahead to step 3:
256 can be fit into 669 2 times, resulting in a remainder of 157.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 512 from 669 and we're left with 157.
Bring next digit (7) of the dividend behind the 157 and repeat the process: 1577 / 256

On to step 4:
If we divide 1577 by 256, we get 6 and a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 1536 from 1577 and we're left with 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 256

Advancing to step 5:
256 goes into 411 1 times with a remainder of 155.
The next digit of our result is 1. 
Result so far: 261.0
Subtract 256 from 411 to get 155.
Include the next digit (1) from the dividend after 155, then repeat: 1551 / 256

Advancing to step 6:
The number 256 fits into 1551 6 times, leaving a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 2616.0
If we take 1536 away from 1551, we end up with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 256

Let's proceed to step 7:
154 divided by 256 is 0 with a remainder of 154.
Put 0 as the next digit of the answer. 
Result so far: 26160.0
The remainder is 154 after subtracting 0 from 154.
Include the next digit (6) from the dividend after 154, then repeat: 1546 / 256

Going ahead to step 8:
256 goes into 1546 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 261606.0
Deduct 1536 from 1546 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 256, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 261606.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
1000 divided by 256 is 3 with a remainder of 232.
The number 3 becomes the next digit in our result. 
Result so far: 261606.03
Subtract 768 from 1000 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 11:
2320 divided by 256 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 261606.039
Subtract 2304 from 2320 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.

Advancing to step 12:
When dividing 160 by 256, we get 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 261606.039
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
When dividing 1600 by 256, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 261606.03906
Subtract 1536 from 1600 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.

Moving on to step 14:
When dividing 640 by 256, we get 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 261606.039062
The remainder is 128 after subtracting 512 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 15:
256 goes into 1280 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 261606.0390625
Subtract 1280 from 1280 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.

Going ahead to step 16:
256 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 261606.0390625
Subtracting 0 from 0 leaves us 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.

Our division results in 261606.0390625 with a remaining 0.0.
