70254731 ÷ 668 
Our goal is to divide 70254731 by 668.

Advancing to step 1:
When dividing 7 by 668, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 668

On to step 2:
When dividing 70 by 668, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 668

Advancing to step 3:
668 can be fit into 702 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 668 from 702, we get 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 668

Let's proceed to step 4:
668 goes into 345 0 times with a remainder of 345.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 345 and we're left with 345.
Bring next digit (4) of the dividend behind the 345 and repeat the process: 3454 / 668

Going ahead to step 5:
668 can be fit into 3454 5 times, resulting in a remainder of 114.
The next digit of our result is 5. 
Result so far: 105.0
Subtract 3340 from 3454 to get 114.
Include the next digit (7) from the dividend after 114, then repeat: 1147 / 668

Moving on to step 6:
668 can be fit into 1147 1 times, resulting in a remainder of 479.
Write down 1 as next digit of the result. 
Result so far: 1051.0
If we subtract 668 from 1147, we get 479.
Take the next digit (3) from the dividend and append it to 479, then repeat: 4793 / 668

Going ahead to step 7:
668 goes into 4793 7 times with a remainder of 117.
The number 7 becomes the next digit in our result. 
Result so far: 10517.0
Deduct 4676 from 4793 and we're left with 117.
Bring next digit (1) of the dividend behind the 117 and repeat the process: 1171 / 668

Going ahead to step 8:
668 can be fit into 1171 1 times, resulting in a remainder of 503.
Record the quotient 1 as the next digit in the result. 
Result so far: 105171.0
Deduct 668 from 1171 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 9:
When dividing 5030 by 668, we get 7 with a remainder of 354.
Put 7 as the next digit of the answer. 
Result so far: 105171.7
Subtract 4676 from 5030 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
The number 668 fits into 3540 5 times, leaving a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 105171.75
If we subtract 3340 from 3540, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
2000 divided by 668 is 2 with a remainder of 664.
Put 2 as the next digit of the answer. 
Result so far: 105171.752
The remainder is 664 after subtracting 1336 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 12:
668 goes into 6640 9 times with a remainder of 628.
The number 9 becomes the next digit in our result. 
Result so far: 105171.7529
Subtracting 6012 from 6640 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 13:
When dividing 6280 by 668, we get 9 with a remainder of 268.
The number 9 becomes the next digit in our result. 
Result so far: 105171.75299
If we subtract 6012 from 6280, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

After the division, we end up with 105171.75299 and a remainder of 0.000268.
