We divide 46518977 by 646
We want to divide 46518977 by 646.

Let's proceed to step 1:
When dividing 4 by 646, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 646

On to step 2:
If we divide 46 by 646, we get 0 and a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 646

Let's proceed to step 3:
If we divide 465 by 646, we get 0 and a remainder of 465.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 465 to get 465.
Grab the next digit (1) from the dividend, add it to 465, then carry on: 4651 / 646

Going ahead to step 4:
If we divide 4651 by 646, we get 7 and a remainder of 129.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 129 after subtracting 4522 from 4651.
Take the next digit (8) from the dividend and append it to 129, then repeat: 1298 / 646

Advancing to step 5:
If we divide 1298 by 646, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 1292 from 1298 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 646

Let's proceed to step 6:
When dividing 69 by 646, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 720.0
If we subtract 0 from 69, we get 69.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 646

Step 7:
697 divided by 646 is 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 7201.0
Deduct 646 from 697 and we're left with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 646

Advancing to step 8:
If we divide 517 by 646, we get 0 and a remainder of 517.
Record the quotient 0 as the next digit in the result. 
Result so far: 72010.0
Subtracting 0 from 517 leaves us with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Moving on to step 9:
If we divide 5170 by 646, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 72010.8
Deduct 5168 from 5170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
646 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 72010.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 646, we get 0 and a remainder of 200.
The next digit of our result is 0. 
Result so far: 72010.8
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 72010.8, with a leftover of 0.02.
