84636976 ÷ 669 
Let's see how many times 669 fits into 84636976.

On to step 1:
669 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 669

On to step 2:
669 goes into 84 0 times with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (6) from the dividend after 84, then repeat: 846 / 669

Let's proceed to step 3:
669 can be fit into 846 1 times, resulting in a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 177 after subtracting 669 from 846.
Append the next digit (3) from the dividend to 177 and continue with: 1773 / 669

Moving on to step 4:
669 can be fit into 1773 2 times, resulting in a remainder of 435.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1338 from 1773 to get 435.
Include the next digit (6) from the dividend after 435, then repeat: 4356 / 669

On to step 5:
If we divide 4356 by 669, we get 6 and a remainder of 342.
Put 6 as the next digit of the answer. 
Result so far: 126.0
If we subtract 4014 from 4356, we get 342.
Grab the next digit (9) from the dividend, add it to 342, then carry on: 3429 / 669

Advancing to step 6:
When dividing 3429 by 669, we get 5 with a remainder of 84.
Record the quotient 5 as the next digit in the result. 
Result so far: 1265.0
If we subtract 3345 from 3429, we get 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 669

Advancing to step 7:
669 can be fit into 847 1 times, resulting in a remainder of 178.
Write down 1 as next digit of the result. 
Result so far: 12651.0
The remainder is 178 after subtracting 669 from 847.
Include the next digit (6) from the dividend after 178, then repeat: 1786 / 669

Let's proceed to step 8:
669 goes into 1786 2 times with a remainder of 448.
The next digit of our result is 2. 
Result so far: 126512.0
If we subtract 1338 from 1786, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 9:
4480 divided by 669 is 6 with a remainder of 466.
Write down 6 as next digit of the result. 
Result so far: 126512.6
Deduct 4014 from 4480 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 10:
669 goes into 4660 6 times with a remainder of 646.
Record the quotient 6 as the next digit in the result. 
Result so far: 126512.66
If we subtract 4014 from 4660, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

After the division, we end up with 126512.66 and a remainder of 0.646.
