845638 ÷ 51 
We want to figure out the number of times 845638 can be divided by 51.

On to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 51

Let's proceed to step 2:
84 divided by 51 is 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 84 leaves us with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 51

On to step 3:
When dividing 335 by 51, we get 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 306 from 335, we get 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 51

Step 4:
The number 51 fits into 296 5 times, leaving a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we subtract 255 from 296, we get 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 51

Going ahead to step 5:
If we divide 413 by 51, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 1658.0
Subtracting 408 from 413 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 51

Step 6:
51 goes into 58 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 16581.0
Subtract 51 from 58 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 51, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 16581.1
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 16581.13
Subtract 153 from 190 to 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.

Step 9:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 16581.137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
If we divide 130 by 51, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 16581.1372
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
51 goes into 280 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 16581.13725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
51 goes into 250 4 times with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 16581.137254
Subtracting 204 from 250 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
51 goes into 460 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 16581.1372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16581.1372549
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 16581.1372549, and the remainder is 1e-08.
