We divide 51679614 by 1
We want to figure out the number of times 51679614 can be divided by 1.

Step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Advancing to step 2:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 51.0
Subtract 1 from 1 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

On to step 3:
6 divided by 1 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 516.0
If we subtract 6 from 6, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Going ahead to step 4:
When dividing 7 by 1, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 5167.0
Subtract 7 from 7 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Step 5:
When dividing 9 by 1, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 51679.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Step 6:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 516796.0
Subtract 6 from 6 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

On to step 7:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 5167961.0
The remainder is 0 after subtracting 1 from 1.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 8:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 51679614.0
If we subtract 4 from 4, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51679614.0
If we take 0 away from 0, we end up 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 10:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51679614.0
If we take 0 away from 0, we end up 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.

After the division, we end up with 51679614.0 and a remainder of 0.0.
