We're dividing 78263991 by 53 
Our goal is to divide 78263991 by 53.

Let's proceed to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 53

On to step 2:
53 goes into 78 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 25 after subtracting 53 from 78.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 53

Advancing to step 3:
53 goes into 252 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 212 from 252 and we're left with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 53

Moving on to step 4:
53 goes into 406 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Deduct 371 from 406 and we're left with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 53

Moving on to step 5:
53 can be fit into 353 6 times, resulting in a remainder of 35.
The next digit of our result is 6. 
Result so far: 1476.0
Subtract 318 from 353 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 53

Going ahead to step 6:
359 divided by 53 is 6 with a remainder of 41.
Write down 6 as next digit of the result. 
Result so far: 14766.0
Subtracting 318 from 359 leaves us with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 53

Step 7:
If we divide 419 by 53, we get 7 and a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 147667.0
If we take 371 away from 419, we end up with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 53

Going ahead to step 8:
If we divide 481 by 53, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 1476679.0
Subtract 477 from 481 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
53 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1476679.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 53 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 1476679.07
Subtract 371 from 400 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
53 goes into 290 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1476679.075
Subtract 265 from 290 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
53 can be fit into 250 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 1476679.0754
Subtract 212 from 250 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 13:
53 goes into 380 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1476679.07547
Deduct 371 from 380 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 14:
90 divided by 53 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1476679.075471
Subtract 53 from 90 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 15:
When dividing 370 by 53, we get 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 1476679.0754716
Deduct 318 from 370 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 16:
520 divided by 53 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 1476679.07547169
If we subtract 477 from 520, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 1476679.07547169 with a balance of 4.3e-08.
