Let's divide 68048591 by 646
We want to figure out the number of times 68048591 can be divided by 646.

Advancing to step 1:
646 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 646

Going ahead to step 2:
If we divide 68 by 646, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 646

Let's proceed to step 3:
680 divided by 646 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 646 from 680 leaves us with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 646

Moving on to step 4:
If we divide 344 by 646, we get 0 and a remainder of 344.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 344 leaves us with 344.
Bring next digit (8) of the dividend behind the 344 and repeat the process: 3448 / 646

On to step 5:
When dividing 3448 by 646, we get 5 with a remainder of 218.
The next digit of our result is 5. 
Result so far: 105.0
Subtract 3230 from 3448 to get 218.
Take the next digit (5) from the dividend and append it to 218, then repeat: 2185 / 646

Moving on to step 6:
646 goes into 2185 3 times with a remainder of 247.
Use 3 as the next digit of our solution. 
Result so far: 1053.0
Deduct 1938 from 2185 and we're left with 247.
Bring next digit (9) of the dividend behind the 247 and repeat the process: 2479 / 646

Going ahead to step 7:
The number 646 fits into 2479 3 times, leaving a remainder of 541.
Write down 3 as next digit of the result. 
Result so far: 10533.0
If we take 1938 away from 2479, we end up with 541.
Grab the next digit (1) from the dividend, add it to 541, then carry on: 5411 / 646

Moving on to step 8:
646 goes into 5411 8 times with a remainder of 243.
The next digit of our result is 8. 
Result so far: 105338.0
Deduct 5168 from 5411 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 9:
If we divide 2430 by 646, we get 3 and a remainder of 492.
Record the quotient 3 as the next digit in the result. 
Result so far: 105338.3
Deduct 1938 from 2430 and we're left with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 10:
When dividing 4920 by 646, we get 7 with a remainder of 398.
The number 7 becomes the next digit in our result. 
Result so far: 105338.37
If we take 4522 away from 4920, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 11:
If we divide 3980 by 646, we get 6 and a remainder of 104.
The next digit of our result is 6. 
Result so far: 105338.376
If we subtract 3876 from 3980, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
When dividing 1040 by 646, we get 1 with a remainder of 394.
Put 1 as the next digit of the answer. 
Result so far: 105338.3761
Subtract 646 from 1040 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 13:
646 can be fit into 3940 6 times, resulting in a remainder of 64.
The next digit of our result is 6. 
Result so far: 105338.37616
Subtracting 3876 from 3940 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
When dividing 640 by 646, we get 0 with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 105338.37616
The remainder is 640 after subtracting 0 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 15:
646 can be fit into 6400 9 times, resulting in a remainder of 586.
Record the quotient 9 as the next digit in the result. 
Result so far: 105338.3761609
If we subtract 5814 from 6400, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 16:
5860 divided by 646 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 105338.37616099
Deduct 5814 from 5860 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 105338.37616099 with a remainder of 4.6e-08.
