We're dividing 77711236 by 661 
Our goal is to divide 77711236 by 661.

Advancing to step 1:
The number 661 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our 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 / 661

Let's proceed to step 2:
When dividing 77 by 661, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 661

Going ahead to step 3:
If we divide 777 by 661, we get 1 and a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 116 after subtracting 661 from 777.
Take the next digit (1) from the dividend and append it to 116, then repeat: 1161 / 661

Going ahead to step 4:
When dividing 1161 by 661, we get 1 with a remainder of 500.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 661 from 1161 and we're left with 500.
Append the next digit (1) from the dividend to 500 and continue with: 5001 / 661

Going ahead to step 5:
If we divide 5001 by 661, we get 7 and a remainder of 374.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 4627 from 5001 leaves us with 374.
Take the next digit (2) from the dividend and append it to 374, then repeat: 3742 / 661

On to step 6:
661 can be fit into 3742 5 times, resulting in a remainder of 437.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
If we take 3305 away from 3742, we end up with 437.
Append the next digit (3) from the dividend to 437 and continue with: 4373 / 661

Step 7:
The number 661 fits into 4373 6 times, leaving a remainder of 407.
The number 6 becomes the next digit in our result. 
Result so far: 11756.0
Subtracting 3966 from 4373 leaves us with 407.
Grab the next digit (6) from the dividend, add it to 407, then carry on: 4076 / 661

Let's proceed to step 8:
661 goes into 4076 6 times with a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 117566.0
If we take 3966 away from 4076, we end up with 110.
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 9:
If we divide 1100 by 661, we get 1 and a remainder of 439.
Write down 1 as next digit of the result. 
Result so far: 117566.1
The remainder is 439 after subtracting 661 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 10:
661 can be fit into 4390 6 times, resulting in a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 117566.16
Deduct 3966 from 4390 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 11:
The number 661 fits into 4240 6 times, leaving a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 117566.166
Subtracting 3966 from 4240 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Our division results in 117566.166 with a remaining 0.0274.
