66193426 divided by 286 
We want to figure out the number of times 66193426 can be divided by 286.

On to step 1:
286 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 286

Moving on to step 2:
286 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 286

Step 3:
286 can be fit into 661 2 times, resulting in a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 572 from 661 to get 89.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 286

Advancing to step 4:
286 goes into 899 3 times with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 41 after subtracting 858 from 899.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 286

Step 5:
286 goes into 413 1 times with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 231.0
Subtracting 286 from 413 leaves us with 127.
Take the next digit (4) from the dividend and append it to 127, then repeat: 1274 / 286

Advancing to step 6:
286 can be fit into 1274 4 times, resulting in a remainder of 130.
The next digit of our result is 4. 
Result so far: 2314.0
Subtract 1144 from 1274 to get 130.
Include the next digit (2) from the dividend after 130, then repeat: 1302 / 286

Going ahead to step 7:
286 goes into 1302 4 times with a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 23144.0
If we take 1144 away from 1302, we end up with 158.
Append the next digit (6) from the dividend to 158 and continue with: 1586 / 286

Let's proceed to step 8:
The number 286 fits into 1586 5 times, leaving a remainder of 156.
Use 5 as the next digit of our solution. 
Result so far: 231445.0
Deduct 1430 from 1586 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 9:
286 can be fit into 1560 5 times, resulting in a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 231445.5
Subtract 1430 from 1560 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
When dividing 1300 by 286, we get 4 with a remainder of 156.
The next digit of our result is 4. 
Result so far: 231445.54
Subtracting 1144 from 1300 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
1560 divided by 286 is 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 231445.545
The remainder is 130 after subtracting 1430 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
When dividing 1300 by 286, we get 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 231445.5454
Subtract 1144 from 1300 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
286 can be fit into 1560 5 times, resulting in a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 231445.54545
Deduct 1430 from 1560 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
286 can be fit into 1300 4 times, resulting in a remainder of 156.
The next digit of our result is 4. 
Result so far: 231445.545454
Deduct 1144 from 1300 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 15:
286 can be fit into 1560 5 times, resulting in a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 231445.5454545
Deduct 1430 from 1560 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 16:
286 can be fit into 1300 4 times, resulting in a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 231445.54545454
The remainder is 156 after subtracting 1144 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final outcome is 231445.54545454, with a leftover of 1.56e-07.
