45463921 ÷ 843 
We want to figure out the number of times 45463921 can be divided by 843.

Going ahead to step 1:
843 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 843

On to step 2:
If we divide 45 by 843, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 843

On to step 3:
843 can be fit into 454 0 times, resulting in a remainder of 454.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 454 to get 454.
Take the next digit (6) from the dividend and append it to 454, then repeat: 4546 / 843

On to step 4:
If we divide 4546 by 843, we get 5 and a remainder of 331.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 331 after subtracting 4215 from 4546.
Fetch the next digit (3) from the dividend, attach it to 331 and continue: 3313 / 843

On to step 5:
The number 843 fits into 3313 3 times, leaving a remainder of 784.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 2529 from 3313 leaves us with 784.
Bring next digit (9) of the dividend behind the 784 and repeat the process: 7849 / 843

On to step 6:
843 can be fit into 7849 9 times, resulting in a remainder of 262.
Put 9 as the next digit of the answer. 
Result so far: 539.0
If we take 7587 away from 7849, we end up with 262.
Fetch the next digit (2) from the dividend, attach it to 262 and continue: 2622 / 843

Going ahead to step 7:
843 can be fit into 2622 3 times, resulting in a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 5393.0
Subtract 2529 from 2622 to get 93.
Bring next digit (1) of the dividend behind the 93 and repeat the process: 931 / 843

Moving on to step 8:
931 divided by 843 is 1 with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 53931.0
Subtracting 843 from 931 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
843 goes into 880 1 times with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 53931.1
If we subtract 843 from 880, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
If we divide 370 by 843, we get 0 and a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 53931.1
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 11:
843 goes into 3700 4 times with a remainder of 328.
Write down 4 as next digit of the result. 
Result so far: 53931.104
If we subtract 3372 from 3700, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
The number 843 fits into 3280 3 times, leaving a remainder of 751.
The next digit of our result is 3. 
Result so far: 53931.1043
Subtracting 2529 from 3280 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Moving on to step 13:
843 can be fit into 7510 8 times, resulting in a remainder of 766.
Use 8 as the next digit of our solution. 
Result so far: 53931.10438
Subtract 6744 from 7510 to get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

On to step 14:
If we divide 7660 by 843, we get 9 and a remainder of 73.
The next digit of our result is 9. 
Result so far: 53931.104389
Deduct 7587 from 7660 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 15:
If we divide 730 by 843, we get 0 and a remainder of 730.
Write down 0 as next digit of the result. 
Result so far: 53931.104389
Deduct 0 from 730 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 16:
7300 divided by 843 is 8 with a remainder of 556.
The next digit of our result is 8. 
Result so far: 53931.10438908
Subtract 6744 from 7300 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

In conclusion, the division gives 53931.10438908 with a balance of 5.56e-07.
