Let's divide 66856489 by 263
We want to figure out the number of times 66856489 can be divided by 263.

Moving on to step 1:
The number 263 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 263

On to step 2:
If we divide 66 by 263, we get 0 and 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.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 263

Let's proceed to step 3:
668 divided by 263 is 2 with a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 526 away from 668, we end up with 142.
Bring next digit (5) of the dividend behind the 142 and repeat the process: 1425 / 263

Advancing to step 4:
When dividing 1425 by 263, we get 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1315 from 1425 to get 110.
Include the next digit (6) from the dividend after 110, then repeat: 1106 / 263

Moving on to step 5:
1106 divided by 263 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
The remainder is 54 after subtracting 1052 from 1106.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 263

Moving on to step 6:
If we divide 544 by 263, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2542.0
If we take 526 away from 544, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 263

Going ahead to step 7:
188 divided by 263 is 0 with a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 25420.0
If we subtract 0 from 188, we get 188.
Take the next digit (9) from the dividend and append it to 188, then repeat: 1889 / 263

Moving on to step 8:
If we divide 1889 by 263, we get 7 and a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 254207.0
If we take 1841 away from 1889, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
When dividing 480 by 263, we get 1 with a remainder of 217.
The next digit of our result is 1. 
Result so far: 254207.1
If we take 263 away from 480, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 10:
When dividing 2170 by 263, we get 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 254207.18
Subtracting 2104 from 2170 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
When dividing 660 by 263, we get 2 with a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 254207.182
If we subtract 526 from 660, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 12:
If we divide 1340 by 263, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 254207.1825
Subtract 1315 from 1340 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
The number 263 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 254207.1825
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
The number 263 fits into 2500 9 times, leaving a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 254207.182509
Subtracting 2367 from 2500 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 15:
If we divide 1330 by 263, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 254207.1825095
Deduct 1315 from 1330 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
The number 263 fits into 150 0 times, leaving a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 254207.1825095
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 254207.1825095, and the remainder is 1.5e-07.
