15201 ÷ 77 
We're looking to find how many times 77 goes into 15201.

On to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 77

Going ahead to step 2:
77 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 77

Let's proceed to step 3:
The number 77 fits into 152 1 times, leaving a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 75 after subtracting 77 from 152.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 77

Let's proceed to step 4:
77 goes into 750 9 times with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 693 from 750 and we're left with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 77

Advancing to step 5:
The number 77 fits into 571 7 times, leaving a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 197.0
The remainder is 32 after subtracting 539 from 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 6:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 197.4
If we subtract 308 from 320, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 77, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 197.41
Subtracting 77 from 120 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
The number 77 fits into 430 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 197.415
The remainder is 45 after subtracting 385 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
77 can be fit into 450 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 197.4155
Deduct 385 from 450 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 197.4155 and a remainder of 0.00065.
