153661 ÷ 77 
We're looking to find how many times 77 goes into 153661.

Let's proceed to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 77

Advancing to step 2:
15 divided by 77 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 77

Advancing to step 3:
153 divided by 77 is 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 77 from 153 to get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 77

Advancing to step 4:
When dividing 766 by 77, we get 9 with a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 73 after subtracting 693 from 766.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 77

Moving on to step 5:
77 can be fit into 736 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 199.0
If we take 693 away from 736, we end up with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 77

Step 6:
431 divided by 77 is 5 with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 1995.0
If we subtract 385 from 431, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
77 can be fit into 460 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 1995.5
If we take 385 away from 460, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 8:
77 goes into 750 9 times with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 1995.59
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
The number 77 fits into 570 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 1995.597
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
When dividing 310 by 77, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1995.5974
If we take 308 away from 310, we end up 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.

Advancing to step 11:
20 divided by 77 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1995.5974
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
The number 77 fits into 200 2 times, leaving a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 1995.597402
If we take 154 away from 200, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
When dividing 460 by 77, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 1995.5974025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
If we divide 750 by 77, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 1995.59740259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 1995.59740259 and a remainder of 5.7e-08.
