Let's divide 45381985 by 843
We're looking to find how many times 843 goes into 45381985.

Step 1:
When dividing 4 by 843, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 843

Step 2:
45 divided by 843 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 843

Moving on to step 3:
843 goes into 453 0 times with a remainder of 453.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 453 after subtracting 0 from 453.
Append the next digit (8) from the dividend to 453 and continue with: 4538 / 843

Let's proceed to step 4:
When dividing 4538 by 843, we get 5 with a remainder of 323.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 4215 from 4538, we get 323.
Bring next digit (1) of the dividend behind the 323 and repeat the process: 3231 / 843

Advancing to step 5:
If we divide 3231 by 843, we get 3 and a remainder of 702.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 2529 away from 3231, we end up with 702.
Fetch the next digit (9) from the dividend, attach it to 702 and continue: 7029 / 843

Going ahead to step 6:
If we divide 7029 by 843, we get 8 and a remainder of 285.
The number 8 becomes the next digit in our result. 
Result so far: 538.0
If we take 6744 away from 7029, we end up with 285.
Fetch the next digit (8) from the dividend, attach it to 285 and continue: 2858 / 843

Going ahead to step 7:
The number 843 fits into 2858 3 times, leaving a remainder of 329.
The number 3 becomes the next digit in our result. 
Result so far: 5383.0
The remainder is 329 after subtracting 2529 from 2858.
Append the next digit (5) from the dividend to 329 and continue with: 3295 / 843

Going ahead to step 8:
The number 843 fits into 3295 3 times, leaving a remainder of 766.
Use 3 as the next digit of our solution. 
Result so far: 53833.0
The remainder is 766 after subtracting 2529 from 3295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Let's proceed to step 9:
If we divide 7660 by 843, we get 9 and a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 53833.9
If we subtract 7587 from 7660, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
If we divide 730 by 843, we get 0 and a remainder of 730.
Use 0 as the next digit of our solution. 
Result so far: 53833.9
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.

Step 11:
When dividing 7300 by 843, we get 8 with a remainder of 556.
Write down 8 as next digit of the result. 
Result so far: 53833.908
Subtracting 6744 from 7300 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 12:
843 goes into 5560 6 times with a remainder of 502.
Write down 6 as next digit of the result. 
Result so far: 53833.9086
If we subtract 5058 from 5560, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 13:
843 goes into 5020 5 times with a remainder of 805.
Use 5 as the next digit of our solution. 
Result so far: 53833.90865
If we subtract 4215 from 5020, we get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Let's proceed to step 14:
843 can be fit into 8050 9 times, resulting in a remainder of 463.
Write down 9 as next digit of the result. 
Result so far: 53833.908659
Deduct 7587 from 8050 and we're left with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 15:
4630 divided by 843 is 5 with a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 53833.9086595
Subtracting 4215 from 4630 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 16:
The number 843 fits into 4150 4 times, leaving a remainder of 778.
The number 4 becomes the next digit in our result. 
Result so far: 53833.90865954
Deduct 3372 from 4150 and we're left with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

After the division, we end up with 53833.90865954 and a remainder of 7.78e-07.
