77051246 divided by 661 
We want to divide 77051246 by 661.

On to step 1:
7 divided by 661 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 661

Moving on to step 2:
661 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 661

Step 3:
770 divided by 661 is 1 with a remainder of 109.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 661 away from 770, we end up with 109.
Bring next digit (5) of the dividend behind the 109 and repeat the process: 1095 / 661

Going ahead to step 4:
When dividing 1095 by 661, we get 1 with a remainder of 434.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 661 from 1095, we get 434.
Fetch the next digit (1) from the dividend, attach it to 434 and continue: 4341 / 661

On to step 5:
4341 divided by 661 is 6 with a remainder of 375.
Write down 6 as next digit of the result. 
Result so far: 116.0
Subtract 3966 from 4341 to get 375.
Bring next digit (2) of the dividend behind the 375 and repeat the process: 3752 / 661

On to step 6:
When dividing 3752 by 661, we get 5 with a remainder of 447.
Put 5 as the next digit of the answer. 
Result so far: 1165.0
If we take 3305 away from 3752, we end up with 447.
Grab the next digit (4) from the dividend, add it to 447, then carry on: 4474 / 661

Let's proceed to step 7:
661 goes into 4474 6 times with a remainder of 508.
Put 6 as the next digit of the answer. 
Result so far: 11656.0
Deduct 3966 from 4474 and we're left with 508.
Bring next digit (6) of the dividend behind the 508 and repeat the process: 5086 / 661

On to step 8:
661 goes into 5086 7 times with a remainder of 459.
Use 7 as the next digit of our solution. 
Result so far: 116567.0
Subtracting 4627 from 5086 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 9:
661 goes into 4590 6 times with a remainder of 624.
The number 6 becomes the next digit in our result. 
Result so far: 116567.6
If we subtract 3966 from 4590, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 10:
When dividing 6240 by 661, we get 9 with a remainder of 291.
The next digit of our result is 9. 
Result so far: 116567.69
Deduct 5949 from 6240 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 11:
The number 661 fits into 2910 4 times, leaving a remainder of 266.
Record the quotient 4 as the next digit in the result. 
Result so far: 116567.694
Deduct 2644 from 2910 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 12:
The number 661 fits into 2660 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 116567.6944
If we subtract 2644 from 2660, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 116567.6944, and the remainder is 0.00016.
