87938642 ÷ 979 
Our goal is to divide 87938642 by 979.

Advancing to step 1:
When dividing 8 by 979, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 979

Moving on to step 2:
979 can be fit into 87 0 times, resulting in a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 979

Let's proceed to step 3:
979 can be fit into 879 0 times, resulting in a remainder of 879.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 879 leaves us with 879.
Append the next digit (3) from the dividend to 879 and continue with: 8793 / 979

Let's proceed to step 4:
8793 divided by 979 is 8 with a remainder of 961.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7832 from 8793 and we're left with 961.
Fetch the next digit (8) from the dividend, attach it to 961 and continue: 9618 / 979

Advancing to step 5:
979 goes into 9618 9 times with a remainder of 807.
The next digit of our result is 9. 
Result so far: 89.0
If we take 8811 away from 9618, we end up with 807.
Fetch the next digit (6) from the dividend, attach it to 807 and continue: 8076 / 979

On to step 6:
The number 979 fits into 8076 8 times, leaving a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 898.0
If we subtract 7832 from 8076, we get 244.
Append the next digit (4) from the dividend to 244 and continue with: 2444 / 979

Moving on to step 7:
When dividing 2444 by 979, we get 2 with a remainder of 486.
Use 2 as the next digit of our solution. 
Result so far: 8982.0
Subtract 1958 from 2444 to get 486.
Include the next digit (2) from the dividend after 486, then repeat: 4862 / 979

Advancing to step 8:
979 goes into 4862 4 times with a remainder of 946.
Write down 4 as next digit of the result. 
Result so far: 89824.0
Subtracting 3916 from 4862 leaves us with 946.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9460, and continue the process.

On to step 9:
If we divide 9460 by 979, we get 9 and a remainder of 649.
Write down 9 as next digit of the result. 
Result so far: 89824.9
Deduct 8811 from 9460 and we're left with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 10:
979 goes into 6490 6 times with a remainder of 616.
Record the quotient 6 as the next digit in the result. 
Result so far: 89824.96
Subtracting 5874 from 6490 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 11:
6160 divided by 979 is 6 with a remainder of 286.
Record the quotient 6 as the next digit in the result. 
Result so far: 89824.966
The remainder is 286 after subtracting 5874 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

After the division, we end up with 89824.966 and a remainder of 0.0286.
