46373501 ÷ 864 
We want to divide 46373501 by 864.

Moving on to step 1:
4 divided by 864 is 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.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 864

Step 2:
The number 864 fits into 46 0 times, leaving a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 864

Advancing to step 3:
463 divided by 864 is 0 with a remainder of 463.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 463, we get 463.
Bring next digit (7) of the dividend behind the 463 and repeat the process: 4637 / 864

Advancing to step 4:
864 goes into 4637 5 times with a remainder of 317.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4320 from 4637 and we're left with 317.
Fetch the next digit (3) from the dividend, attach it to 317 and continue: 3173 / 864

Going ahead to step 5:
If we divide 3173 by 864, we get 3 and a remainder of 581.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtracting 2592 from 3173 leaves us with 581.
Bring next digit (5) of the dividend behind the 581 and repeat the process: 5815 / 864

Step 6:
The number 864 fits into 5815 6 times, leaving a remainder of 631.
Use 6 as the next digit of our solution. 
Result so far: 536.0
Deduct 5184 from 5815 and we're left with 631.
Append the next digit (0) from the dividend to 631 and continue with: 6310 / 864

Step 7:
When dividing 6310 by 864, we get 7 with a remainder of 262.
The next digit of our result is 7. 
Result so far: 5367.0
The remainder is 262 after subtracting 6048 from 6310.
Fetch the next digit (1) from the dividend, attach it to 262 and continue: 2621 / 864

Moving on to step 8:
When dividing 2621 by 864, we get 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 53673.0
If we subtract 2592 from 2621, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
The number 864 fits into 290 0 times, leaving a remainder of 290.
The next digit of our result is 0. 
Result so far: 53673.0
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
864 can be fit into 2900 3 times, resulting in a remainder of 308.
Put 3 as the next digit of the answer. 
Result so far: 53673.03
The remainder is 308 after subtracting 2592 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 11:
The number 864 fits into 3080 3 times, leaving a remainder of 488.
Write down 3 as next digit of the result. 
Result so far: 53673.033
Deduct 2592 from 3080 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final outcome is 53673.033, with a leftover of 0.0488.
