We're dividing 53511372 by 771 
We want to divide 53511372 by 771.

On to step 1:
The number 771 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 771

Moving on to step 2:
If we divide 53 by 771, we get 0 and a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 771

Advancing to step 3:
771 goes into 535 0 times with a remainder of 535.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 535, we get 535.
Append the next digit (1) from the dividend to 535 and continue with: 5351 / 771

Let's proceed to step 4:
When dividing 5351 by 771, we get 6 with a remainder of 725.
The next digit of our result is 6. 
Result so far: 6.0
If we take 4626 away from 5351, we end up with 725.
Include the next digit (1) from the dividend after 725, then repeat: 7251 / 771

Going ahead to step 5:
When dividing 7251 by 771, we get 9 with a remainder of 312.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtract 6939 from 7251 to get 312.
Grab the next digit (3) from the dividend, add it to 312, then carry on: 3123 / 771

Let's proceed to step 6:
771 goes into 3123 4 times with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 694.0
Subtract 3084 from 3123 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 771

Step 7:
771 goes into 397 0 times with a remainder of 397.
The next digit of our result is 0. 
Result so far: 6940.0
Subtracting 0 from 397 leaves us with 397.
Bring next digit (2) of the dividend behind the 397 and repeat the process: 3972 / 771

Advancing to step 8:
When dividing 3972 by 771, we get 5 with a remainder of 117.
The number 5 becomes the next digit in our result. 
Result so far: 69405.0
Deduct 3855 from 3972 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
771 goes into 1170 1 times with a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 69405.1
Subtracting 771 from 1170 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 10:
3990 divided by 771 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 69405.15
The remainder is 135 after subtracting 3855 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 11:
771 goes into 1350 1 times with a remainder of 579.
Use 1 as the next digit of our solution. 
Result so far: 69405.151
If we subtract 771 from 1350, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Let's proceed to step 12:
When dividing 5790 by 771, we get 7 with a remainder of 393.
Write down 7 as next digit of the result. 
Result so far: 69405.1517
The remainder is 393 after subtracting 5397 from 5790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 13:
The number 771 fits into 3930 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 69405.15175
Deduct 3855 from 3930 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
771 can be fit into 750 0 times, resulting in a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 69405.15175
If we take 0 away from 750, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 15:
The number 771 fits into 7500 9 times, leaving a remainder of 561.
Record the quotient 9 as the next digit in the result. 
Result so far: 69405.1517509
The remainder is 561 after subtracting 6939 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 16:
771 goes into 5610 7 times with a remainder of 213.
Write down 7 as next digit of the result. 
Result so far: 69405.15175097
Subtract 5397 from 5610 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Our division results in 69405.15175097 with a remaining 2.13e-07.
