67668139 ÷ 954 
Our goal is to divide 67668139 by 954.

Let's proceed to step 1:
954 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 954

Going ahead to step 2:
If we divide 67 by 954, we get 0 and a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 954

Let's proceed to step 3:
If we divide 676 by 954, we get 0 and a remainder of 676.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 676 leaves us with 676.
Append the next digit (6) from the dividend to 676 and continue with: 6766 / 954

Step 4:
6766 divided by 954 is 7 with a remainder of 88.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 6678 from 6766 to get 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 954

On to step 5:
The number 954 fits into 888 0 times, leaving a remainder of 888.
Write down 0 as next digit of the result. 
Result so far: 70.0
Subtracting 0 from 888 leaves us with 888.
Grab the next digit (1) from the dividend, add it to 888, then carry on: 8881 / 954

On to step 6:
954 can be fit into 8881 9 times, resulting in a remainder of 295.
Put 9 as the next digit of the answer. 
Result so far: 709.0
The remainder is 295 after subtracting 8586 from 8881.
Grab the next digit (3) from the dividend, add it to 295, then carry on: 2953 / 954

Step 7:
2953 divided by 954 is 3 with a remainder of 91.
Write down 3 as next digit of the result. 
Result so far: 7093.0
Subtract 2862 from 2953 to get 91.
Fetch the next digit (9) from the dividend, attach it to 91 and continue: 919 / 954

Going ahead to step 8:
919 divided by 954 is 0 with a remainder of 919.
Record the quotient 0 as the next digit in the result. 
Result so far: 70930.0
Deduct 0 from 919 and we're left with 919.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9190, and continue the process.

Advancing to step 9:
The number 954 fits into 9190 9 times, leaving a remainder of 604.
The number 9 becomes the next digit in our result. 
Result so far: 70930.9
The remainder is 604 after subtracting 8586 from 9190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 10:
If we divide 6040 by 954, we get 6 and a remainder of 316.
The number 6 becomes the next digit in our result. 
Result so far: 70930.96
If we subtract 5724 from 6040, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 11:
The number 954 fits into 3160 3 times, leaving a remainder of 298.
Use 3 as the next digit of our solution. 
Result so far: 70930.963
Deduct 2862 from 3160 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 12:
954 can be fit into 2980 3 times, resulting in a remainder of 118.
Record the quotient 3 as the next digit in the result. 
Result so far: 70930.9633
If we take 2862 away from 2980, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

After the division, we end up with 70930.9633 and a remainder of 0.00118.
