Let's divide 46520168 by 646
We want to figure out the number of times 46520168 can be divided by 646.

Going ahead to step 1:
The number 646 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 646

On to step 2:
The number 646 fits into 46 0 times, leaving a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 646

Going ahead to step 3:
When dividing 465 by 646, we get 0 with a remainder of 465.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 465 and we're left with 465.
Append the next digit (2) from the dividend to 465 and continue with: 4652 / 646

On to step 4:
When dividing 4652 by 646, we get 7 with a remainder of 130.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 4522 from 4652, we get 130.
Append the next digit (0) from the dividend to 130 and continue with: 1300 / 646

Let's proceed to step 5:
646 goes into 1300 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 72.0
If we take 1292 away from 1300, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 646

Moving on to step 6:
81 divided by 646 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 720.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 646

Advancing to step 7:
If we divide 816 by 646, we get 1 and a remainder of 170.
Write down 1 as next digit of the result. 
Result so far: 7201.0
Subtracting 646 from 816 leaves us with 170.
Append the next digit (8) from the dividend to 170 and continue with: 1708 / 646

Going ahead to step 8:
The number 646 fits into 1708 2 times, leaving a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 72012.0
Deduct 1292 from 1708 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 9:
4160 divided by 646 is 6 with a remainder of 284.
The next digit of our result is 6. 
Result so far: 72012.6
If we subtract 3876 from 4160, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 10:
646 goes into 2840 4 times with a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 72012.64
If we take 2584 away from 2840, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 11:
646 goes into 2560 3 times with a remainder of 622.
The number 3 becomes the next digit in our result. 
Result so far: 72012.643
If we take 1938 away from 2560, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 12:
If we divide 6220 by 646, we get 9 and a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 72012.6439
The remainder is 406 after subtracting 5814 from 6220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 13:
4060 divided by 646 is 6 with a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 72012.64396
If we take 3876 away from 4060, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 14:
646 goes into 1840 2 times with a remainder of 548.
Record the quotient 2 as the next digit in the result. 
Result so far: 72012.643962
If we subtract 1292 from 1840, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 15:
5480 divided by 646 is 8 with a remainder of 312.
The next digit of our result is 8. 
Result so far: 72012.6439628
The remainder is 312 after subtracting 5168 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 16:
646 goes into 3120 4 times with a remainder of 536.
The number 4 becomes the next digit in our result. 
Result so far: 72012.64396284
If we subtract 2584 from 3120, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

In conclusion, the division gives 72012.64396284 with a balance of 5.36e-07.
