53689429 divided by 880 
Our goal is to divide 53689429 by 880.

On to step 1:
If we divide 5 by 880, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 880

Going ahead to step 2:
If we divide 53 by 880, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 880

On to step 3:
If we divide 536 by 880, we get 0 and a remainder of 536.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 536 after subtracting 0 from 536.
Bring next digit (8) of the dividend behind the 536 and repeat the process: 5368 / 880

Going ahead to step 4:
880 can be fit into 5368 6 times, resulting in a remainder of 88.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 5280 from 5368, we get 88.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 880

Going ahead to step 5:
The number 880 fits into 889 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we subtract 880 from 889, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 880

Moving on to step 6:
When dividing 94 by 880, we get 0 with a remainder of 94.
Write down 0 as next digit of the result. 
Result so far: 610.0
Subtracting 0 from 94 leaves us with 94.
Take the next digit (2) from the dividend and append it to 94, then repeat: 942 / 880

On to step 7:
880 can be fit into 942 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 6101.0
Subtracting 880 from 942 leaves us with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 880

Let's proceed to step 8:
880 goes into 629 0 times with a remainder of 629.
Record the quotient 0 as the next digit in the result. 
Result so far: 61010.0
If we subtract 0 from 629, we get 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Moving on to step 9:
880 can be fit into 6290 7 times, resulting in a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 61010.7
The remainder is 130 after subtracting 6160 from 6290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
880 can be fit into 1300 1 times, resulting in a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 61010.71
If we take 880 away from 1300, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
4200 divided by 880 is 4 with a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 61010.714
Deduct 3520 from 4200 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 12:
6800 divided by 880 is 7 with a remainder of 640.
The number 7 becomes the next digit in our result. 
Result so far: 61010.7147
If we subtract 6160 from 6800, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
The number 880 fits into 6400 7 times, leaving a remainder of 240.
Use 7 as the next digit of our solution. 
Result so far: 61010.71477
If we subtract 6160 from 6400, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 61010.71477 with a remainder of 0.00024.
