Let's divide 525257 by 77
We want to figure out the number of times 525257 can be divided by 77.

Step 1:
5 divided by 77 is 0 with 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.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 77

On 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
Subtracting 0 from 52 leaves us with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 77

Step 3:
77 can be fit into 525 6 times, resulting in a remainder of 63.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 462 from 525 to get 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 77

On to step 4:
When dividing 632 by 77, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 68.0
If we subtract 616 from 632, we get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 77

Moving on to step 5:
77 goes into 165 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 682.0
If we take 154 away from 165, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 77

Moving on to step 6:
The number 77 fits into 117 1 times, leaving a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 6821.0
If we subtract 77 from 117, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
77 goes into 400 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6821.5
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 77, we get 1 and a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 6821.51
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
When dividing 730 by 77, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 6821.519
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
If we divide 370 by 77, we get 4 and a remainder of 62.
The next digit of our result is 4. 
Result so far: 6821.5194
Subtract 308 from 370 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
77 goes into 620 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 6821.51948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
77 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6821.51948
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
77 can be fit into 400 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6821.5194805
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
77 goes into 150 1 times with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 6821.51948051
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 6821.51948051, and the remainder is 7.3e-08.
