We're dividing 63690349 by 4 
We want to figure out the number of times 63690349 can be divided by 4.

Step 1:
If we divide 6 by 4, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 4

Advancing to step 2:
4 goes into 23 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 20 away from 23, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 4

Moving on to step 3:
When dividing 36 by 4, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 159.0
Subtracting 36 from 36 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Moving on to step 4:
4 goes into 9 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 1592.0
If we subtract 8 from 9, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

On to step 5:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 15922.0
If we take 8 away from 10, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 4

Moving on to step 6:
4 can be fit into 23 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 159225.0
Subtracting 20 from 23 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 4

Step 7:
The number 4 fits into 34 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 1592258.0
Deduct 32 from 34 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 4

Advancing to step 8:
When dividing 29 by 4, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 15922587.0
Deduct 28 from 29 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 15922587.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15922587.25
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15922587.25
Subtract 0 from 0 to 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 12:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15922587.25
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.

Our division results in 15922587.25 with a remaining 0.0.
