Let's divide 52139279 by 77
We're looking to find how many times 77 goes into 52139279.

On to step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 77

Let's proceed to step 2:
When dividing 52 by 77, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 77

Let's proceed to step 3:
The number 77 fits into 521 6 times, leaving a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 462 from 521 and we're left with 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 77

Step 4:
The number 77 fits into 593 7 times, leaving a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we take 539 away from 593, we end up with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 77

Moving on to step 5:
77 can be fit into 549 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 677.0
If we subtract 539 from 549, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 77

Going ahead to step 6:
When dividing 102 by 77, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 6771.0
If we take 77 away from 102, we end up with 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 77

Going ahead to step 7:
When dividing 257 by 77, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 67713.0
Deduct 231 from 257 and we're left with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 77

Advancing to step 8:
The number 77 fits into 269 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 677133.0
The remainder is 38 after subtracting 231 from 269.
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 9:
380 divided by 77 is 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 677133.4
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.

Going ahead to step 10:
If we divide 720 by 77, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 677133.49
If we take 693 away from 720, we end up 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.

Advancing to step 11:
If we divide 270 by 77, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 677133.493
If we take 231 away from 270, we end up 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.

On to step 12:
When dividing 390 by 77, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 677133.4935
If we take 385 away from 390, we end up 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.

Moving on to step 13:
If we divide 50 by 77, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 677133.4935
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.

Advancing to step 14:
500 divided by 77 is 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 677133.493506
Subtract 462 from 500 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.

Advancing to step 15:
The number 77 fits into 380 4 times, leaving a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 677133.4935064
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.

Moving on to step 16:
77 goes into 720 9 times with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 677133.49350649
If we take 693 away from 720, we end up 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.

The final outcome is 677133.49350649, with a leftover of 2.7e-08.
