We divide 64140191 by 77
Let's see how many times 77 fits into 64140191.

Step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 77

Let's proceed to step 2:
If we divide 64 by 77, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 77

Step 3:
641 divided by 77 is 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 616 from 641 and we're left with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 77

Let's proceed to step 4:
If we divide 254 by 77, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 23 after subtracting 231 from 254.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 77

Going ahead to step 5:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 832.0
If we take 154 away from 230, we end up with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 77

Moving on to step 6:
77 can be fit into 761 9 times, resulting in a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 8329.0
Subtracting 693 from 761 leaves us with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 77

Going ahead to step 7:
689 divided by 77 is 8 with a remainder of 73.
The next digit of our result is 8. 
Result so far: 83298.0
Subtracting 616 from 689 leaves us with 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 77

On to step 8:
When dividing 731 by 77, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 832989.0
Subtract 693 from 731 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
77 goes into 380 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 832989.4
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
If we divide 720 by 77, we get 9 and a remainder of 27.
The next digit of our result is 9. 
Result so far: 832989.49
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
If we divide 270 by 77, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 832989.493
Deduct 231 from 270 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
The number 77 fits into 390 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 832989.4935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
77 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 832989.4935
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
77 goes into 500 6 times with a remainder of 38.
The next digit of our result is 6. 
Result so far: 832989.493506
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 15:
77 goes into 380 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 832989.4935064
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 16:
If we divide 720 by 77, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 832989.49350649
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 832989.49350649, with a leftover of 2.7e-08.
