We're dividing 77664342 by 155 
We're looking to find how many times 155 goes into 77664342.

Let's proceed to step 1:
When dividing 7 by 155, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 155

Going ahead to step 2:
The number 155 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 155

Step 3:
When dividing 776 by 155, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 775 from 776 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 155

Step 4:
155 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 16 to get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 155

On to step 5:
155 can be fit into 164 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 501.0
Subtracting 155 from 164 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 155

Step 6:
155 can be fit into 93 0 times, resulting in a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 5010.0
The remainder is 93 after subtracting 0 from 93.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 155

On to step 7:
934 divided by 155 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 50106.0
If we subtract 930 from 934, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 155

Going ahead to step 8:
When dividing 42 by 155, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 501060.0
Subtract 0 from 42 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
420 divided by 155 is 2 with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 501060.2
The remainder is 110 after subtracting 310 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
155 can be fit into 1100 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 501060.27
Deduct 1085 from 1100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
155 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 501060.27
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
When dividing 1500 by 155, we get 9 with a remainder of 105.
The next digit of our result is 9. 
Result so far: 501060.2709
Subtract 1395 from 1500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
If we divide 1050 by 155, we get 6 and a remainder of 120.
The next digit of our result is 6. 
Result so far: 501060.27096
Subtracting 930 from 1050 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
When dividing 1200 by 155, we get 7 with a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 501060.270967
Subtract 1085 from 1200 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 15:
155 goes into 1150 7 times with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 501060.2709677
Subtracting 1085 from 1150 leaves us 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.

The quotient of the division is 501060.2709677, and the remainder is 6.5e-07.
