78654964 divided by 661 
Let's see how many times 661 fits into 78654964.

Step 1:
661 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 661

Moving on to step 2:
When dividing 78 by 661, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 661

Advancing to step 3:
The number 661 fits into 786 1 times, leaving a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 125 after subtracting 661 from 786.
Fetch the next digit (5) from the dividend, attach it to 125 and continue: 1255 / 661

Step 4:
The number 661 fits into 1255 1 times, leaving a remainder of 594.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 594 after subtracting 661 from 1255.
Append the next digit (4) from the dividend to 594 and continue with: 5944 / 661

Advancing to step 5:
661 goes into 5944 8 times with a remainder of 656.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtract 5288 from 5944 to get 656.
Include the next digit (9) from the dividend after 656, then repeat: 6569 / 661

Going ahead to step 6:
The number 661 fits into 6569 9 times, leaving a remainder of 620.
Use 9 as the next digit of our solution. 
Result so far: 1189.0
Subtracting 5949 from 6569 leaves us with 620.
Bring next digit (6) of the dividend behind the 620 and repeat the process: 6206 / 661

Let's proceed to step 7:
6206 divided by 661 is 9 with a remainder of 257.
Write down 9 as next digit of the result. 
Result so far: 11899.0
Deduct 5949 from 6206 and we're left with 257.
Fetch the next digit (4) from the dividend, attach it to 257 and continue: 2574 / 661

Going ahead to step 8:
2574 divided by 661 is 3 with a remainder of 591.
The number 3 becomes the next digit in our result. 
Result so far: 118993.0
If we subtract 1983 from 2574, we get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 9:
When dividing 5910 by 661, we get 8 with a remainder of 622.
Put 8 as the next digit of the answer. 
Result so far: 118993.8
Deduct 5288 from 5910 and we're left with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 10:
If we divide 6220 by 661, we get 9 and a remainder of 271.
Put 9 as the next digit of the answer. 
Result so far: 118993.89
The remainder is 271 after subtracting 5949 from 6220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Going ahead to step 11:
2710 divided by 661 is 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 118993.894
If we subtract 2644 from 2710, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 12:
661 goes into 660 0 times with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 118993.894
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 13:
6600 divided by 661 is 9 with a remainder of 651.
Use 9 as the next digit of our solution. 
Result so far: 118993.89409
The remainder is 651 after subtracting 5949 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Step 14:
If we divide 6510 by 661, we get 9 and a remainder of 561.
Put 9 as the next digit of the answer. 
Result so far: 118993.894099
Subtracting 5949 from 6510 leaves us with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

The final result is 118993.894099 with a remainder of 5.61e-05.
