51585994 ÷ 105 
We're looking to find how many times 105 goes into 51585994.

Let's proceed to step 1:
The number 105 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 105

Let's proceed to step 2:
105 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 105

Going ahead to step 3:
105 goes into 515 4 times with a remainder of 95.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 420 from 515 leaves us with 95.
Bring next digit (8) of the dividend behind the 95 and repeat the process: 958 / 105

Going ahead to step 4:
If we divide 958 by 105, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Deduct 945 from 958 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 105

On to step 5:
When dividing 135 by 105, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 491.0
If we take 105 away from 135, we end up with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 105

Moving on to step 6:
105 goes into 309 2 times with a remainder of 99.
Write down 2 as next digit of the result. 
Result so far: 4912.0
Deduct 210 from 309 and we're left with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 105

Advancing to step 7:
105 goes into 999 9 times with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 49129.0
Subtract 945 from 999 to get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 105

Step 8:
544 divided by 105 is 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 491295.0
If we subtract 525 from 544, 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.

Let's proceed to step 9:
190 divided by 105 is 1 with a remainder of 85.
The number 1 becomes the next digit in our result. 
Result so far: 491295.1
If we subtract 105 from 190, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 10:
105 can be fit into 850 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 491295.18
If we take 840 away from 850, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
100 divided by 105 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 491295.18
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
The number 105 fits into 1000 9 times, leaving a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 491295.1809
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
105 can be fit into 550 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 491295.18095
The remainder is 25 after subtracting 525 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
105 goes into 250 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 491295.180952
The remainder is 40 after subtracting 210 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
When dividing 400 by 105, we get 3 with a remainder of 85.
The next digit of our result is 3. 
Result so far: 491295.1809523
If we take 315 away from 400, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 16:
When dividing 850 by 105, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 491295.18095238
The remainder is 10 after subtracting 840 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 491295.18095238 and a remainder of 1e-08.
