66194041 ÷ 538 
We want to divide 66194041 by 538.

Moving on to step 1:
If we divide 6 by 538, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 538

Step 2:
The number 538 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 538

Advancing to step 3:
661 divided by 538 is 1 with a remainder of 123.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 538 away from 661, we end up with 123.
Grab the next digit (9) from the dividend, add it to 123, then carry on: 1239 / 538

Going ahead to step 4:
The number 538 fits into 1239 2 times, leaving a remainder of 163.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 1076 from 1239 to get 163.
Fetch the next digit (4) from the dividend, attach it to 163 and continue: 1634 / 538

Let's proceed to step 5:
1634 divided by 538 is 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtract 1614 from 1634 to get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 538

Step 6:
If we divide 200 by 538, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 1230.0
Deduct 0 from 200 and we're left with 200.
Include the next digit (4) from the dividend after 200, then repeat: 2004 / 538

On to step 7:
538 goes into 2004 3 times with a remainder of 390.
The number 3 becomes the next digit in our result. 
Result so far: 12303.0
Subtract 1614 from 2004 to get 390.
Fetch the next digit (1) from the dividend, attach it to 390 and continue: 3901 / 538

Advancing to step 8:
3901 divided by 538 is 7 with a remainder of 135.
The next digit of our result is 7. 
Result so far: 123037.0
Subtracting 3766 from 3901 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 9:
538 can be fit into 1350 2 times, resulting in a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 123037.2
If we subtract 1076 from 1350, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 10:
The number 538 fits into 2740 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 123037.25
If we subtract 2690 from 2740, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
538 goes into 500 0 times with a remainder of 500.
The next digit of our result is 0. 
Result so far: 123037.25
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
The number 538 fits into 5000 9 times, leaving a remainder of 158.
The number 9 becomes the next digit in our result. 
Result so far: 123037.2509
If we subtract 4842 from 5000, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 13:
538 goes into 1580 2 times with a remainder of 504.
Write down 2 as next digit of the result. 
Result so far: 123037.25092
Subtracting 1076 from 1580 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 14:
5040 divided by 538 is 9 with a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 123037.250929
The remainder is 198 after subtracting 4842 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 15:
538 goes into 1980 3 times with a remainder of 366.
The next digit of our result is 3. 
Result so far: 123037.2509293
If we take 1614 away from 1980, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Advancing to step 16:
The number 538 fits into 3660 6 times, leaving a remainder of 432.
Write down 6 as next digit of the result. 
Result so far: 123037.25092936
If we take 3228 away from 3660, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

In conclusion, the division gives 123037.25092936 with a balance of 4.32e-07.
