We look at the division of 46483928 by 645 
We're looking to find how many times 645 goes into 46483928.

Let's proceed to step 1:
If we divide 4 by 645, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 645

Going ahead to step 2:
645 can be fit into 46 0 times, resulting in 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.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 645

Let's proceed to step 3:
464 divided by 645 is 0 with a remainder of 464.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 464 leaves us with 464.
Fetch the next digit (8) from the dividend, attach it to 464 and continue: 4648 / 645

On to step 4:
645 goes into 4648 7 times with a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4515 from 4648, we get 133.
Fetch the next digit (3) from the dividend, attach it to 133 and continue: 1333 / 645

On to step 5:
645 can be fit into 1333 2 times, resulting in a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 1290 from 1333 leaves us with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 645

Moving on to step 6:
645 can be fit into 439 0 times, resulting in a remainder of 439.
The next digit of our result is 0. 
Result so far: 720.0
Deduct 0 from 439 and we're left with 439.
Include the next digit (2) from the dividend after 439, then repeat: 4392 / 645

Let's proceed to step 7:
4392 divided by 645 is 6 with a remainder of 522.
Use 6 as the next digit of our solution. 
Result so far: 7206.0
If we take 3870 away from 4392, we end up with 522.
Bring next digit (8) of the dividend behind the 522 and repeat the process: 5228 / 645

Let's proceed to step 8:
645 goes into 5228 8 times with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 72068.0
Subtracting 5160 from 5228 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
645 goes into 680 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 72068.1
Deduct 645 from 680 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
When dividing 350 by 645, we get 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 72068.1
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
645 goes into 3500 5 times with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 72068.105
Subtract 3225 from 3500 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 12:
When dividing 2750 by 645, we get 4 with a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 72068.1054
The remainder is 170 after subtracting 2580 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
645 goes into 1700 2 times with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 72068.10542
If we subtract 1290 from 1700, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 14:
When dividing 4100 by 645, we get 6 with a remainder of 230.
Use 6 as the next digit of our solution. 
Result so far: 72068.105426
Deduct 3870 from 4100 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 15:
The number 645 fits into 2300 3 times, leaving a remainder of 365.
Write down 3 as next digit of the result. 
Result so far: 72068.1054263
If we take 1935 away from 2300, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 16:
645 goes into 3650 5 times with a remainder of 425.
Put 5 as the next digit of the answer. 
Result so far: 72068.10542635
Subtracting 3225 from 3650 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

In conclusion, the division gives 72068.10542635 with a balance of 4.25e-07.
