70838559 divided by 668 
Let's see how many times 668 fits into 70838559.

On to step 1:
The number 668 fits into 7 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 668

Step 2:
The number 668 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 668

Step 3:
668 goes into 708 1 times with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 668 from 708 to get 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 668

Step 4:
When dividing 403 by 668, we get 0 with a remainder of 403.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 403 leaves us with 403.
Append the next digit (8) from the dividend to 403 and continue with: 4038 / 668

On to step 5:
The number 668 fits into 4038 6 times, leaving a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtract 4008 from 4038 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 668

Step 6:
If we divide 305 by 668, we get 0 and a remainder of 305.
Write down 0 as next digit of the result. 
Result so far: 1060.0
Deduct 0 from 305 and we're left with 305.
Take the next digit (5) from the dividend and append it to 305, then repeat: 3055 / 668

Advancing to step 7:
If we divide 3055 by 668, we get 4 and a remainder of 383.
Use 4 as the next digit of our solution. 
Result so far: 10604.0
Subtract 2672 from 3055 to get 383.
Include the next digit (9) from the dividend after 383, then repeat: 3839 / 668

Let's proceed to step 8:
668 goes into 3839 5 times with a remainder of 499.
Record the quotient 5 as the next digit in the result. 
Result so far: 106045.0
Subtract 3340 from 3839 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Advancing to step 9:
668 can be fit into 4990 7 times, resulting in a remainder of 314.
The number 7 becomes the next digit in our result. 
Result so far: 106045.7
Subtracting 4676 from 4990 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 10:
3140 divided by 668 is 4 with a remainder of 468.
Put 4 as the next digit of the answer. 
Result so far: 106045.74
The remainder is 468 after subtracting 2672 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 11:
If we divide 4680 by 668, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 106045.747
Deduct 4676 from 4680 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 668 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 106045.747
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
The number 668 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 106045.747
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 106045.747 and a remainder of 0.0004.
