51696855 ÷ 105 
Our goal is to divide 51696855 by 105.

Moving on to step 1:
105 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 105

Moving on to step 2:
When dividing 51 by 105, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 105

Advancing to step 3:
If we divide 516 by 105, we get 4 and a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 96 after subtracting 420 from 516.
Include the next digit (9) from the dividend after 96, then repeat: 969 / 105

Step 4:
969 divided by 105 is 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 945 away from 969, we end up with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 105

Going ahead to step 5:
246 divided by 105 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 492.0
If we take 210 away from 246, we end up with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 105

Moving on to step 6:
The number 105 fits into 368 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 4923.0
The remainder is 53 after subtracting 315 from 368.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 105

Let's proceed to step 7:
The number 105 fits into 535 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 49235.0
Subtracting 525 from 535 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 105

Let's proceed to step 8:
The number 105 fits into 105 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 492351.0
Deduct 105 from 105 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 105 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 492351.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 105 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 492351.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 492351.0, with a leftover of 0.0.
