Let's divide 66939955 by 636
Our goal is to divide 66939955 by 636.

Moving on to step 1:
636 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 636

Going ahead to step 2:
66 divided by 636 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 636

Going ahead to step 3:
If we divide 669 by 636, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 636 away from 669, we end up with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 636

Going ahead to step 4:
636 goes into 333 0 times with a remainder of 333.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 333 and we're left with 333.
Append the next digit (9) from the dividend to 333 and continue with: 3339 / 636

On to step 5:
636 goes into 3339 5 times with a remainder of 159.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
The remainder is 159 after subtracting 3180 from 3339.
Bring next digit (9) of the dividend behind the 159 and repeat the process: 1599 / 636

On to step 6:
When dividing 1599 by 636, we get 2 with a remainder of 327.
Put 2 as the next digit of the answer. 
Result so far: 1052.0
If we take 1272 away from 1599, we end up with 327.
Take the next digit (5) from the dividend and append it to 327, then repeat: 3275 / 636

Let's proceed to step 7:
If we divide 3275 by 636, we get 5 and a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 10525.0
If we take 3180 away from 3275, we end up with 95.
Grab the next digit (5) from the dividend, add it to 95, then carry on: 955 / 636

Advancing to step 8:
If we divide 955 by 636, we get 1 and a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 105251.0
If we take 636 away from 955, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 9:
The number 636 fits into 3190 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 105251.5
If we take 3180 away from 3190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 636 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 105251.5
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
The number 636 fits into 1000 1 times, leaving a remainder of 364.
The next digit of our result is 1. 
Result so far: 105251.501
If we take 636 away from 1000, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 12:
The number 636 fits into 3640 5 times, leaving a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 105251.5015
Deduct 3180 from 3640 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 13:
636 can be fit into 4600 7 times, resulting in a remainder of 148.
Use 7 as the next digit of our solution. 
Result so far: 105251.50157
The remainder is 148 after subtracting 4452 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 14:
The number 636 fits into 1480 2 times, leaving a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 105251.501572
Subtracting 1272 from 1480 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 15:
2080 divided by 636 is 3 with a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 105251.5015723
Subtract 1908 from 2080 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 16:
When dividing 1720 by 636, we get 2 with a remainder of 448.
The next digit of our result is 2. 
Result so far: 105251.50157232
Deduct 1272 from 1720 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 105251.50157232, with a leftover of 4.48e-07.
