55772431 divided by 900 
We want to figure out the number of times 55772431 can be divided by 900.

Advancing to step 1:
5 divided by 900 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 900

Step 2:
When dividing 55 by 900, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 900

Advancing to step 3:
When dividing 557 by 900, we get 0 with a remainder of 557.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 557, we end up with 557.
Bring next digit (7) of the dividend behind the 557 and repeat the process: 5577 / 900

Advancing to step 4:
900 goes into 5577 6 times with a remainder of 177.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 177 after subtracting 5400 from 5577.
Take the next digit (2) from the dividend and append it to 177, then repeat: 1772 / 900

Step 5:
900 can be fit into 1772 1 times, resulting in a remainder of 872.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we subtract 900 from 1772, we get 872.
Bring next digit (4) of the dividend behind the 872 and repeat the process: 8724 / 900

On to step 6:
900 can be fit into 8724 9 times, resulting in a remainder of 624.
Use 9 as the next digit of our solution. 
Result so far: 619.0
If we subtract 8100 from 8724, we get 624.
Grab the next digit (3) from the dividend, add it to 624, then carry on: 6243 / 900

Advancing to step 7:
The number 900 fits into 6243 6 times, leaving a remainder of 843.
Record the quotient 6 as the next digit in the result. 
Result so far: 6196.0
The remainder is 843 after subtracting 5400 from 6243.
Grab the next digit (1) from the dividend, add it to 843, then carry on: 8431 / 900

Going ahead to step 8:
When dividing 8431 by 900, we get 9 with a remainder of 331.
The next digit of our result is 9. 
Result so far: 61969.0
Deduct 8100 from 8431 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 9:
900 goes into 3310 3 times with a remainder of 610.
Use 3 as the next digit of our solution. 
Result so far: 61969.3
Deduct 2700 from 3310 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 10:
6100 divided by 900 is 6 with a remainder of 700.
Write down 6 as next digit of the result. 
Result so far: 61969.36
The remainder is 700 after subtracting 5400 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
If we divide 7000 by 900, we get 7 and a remainder of 700.
Put 7 as the next digit of the answer. 
Result so far: 61969.367
Subtracting 6300 from 7000 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 12:
900 can be fit into 7000 7 times, resulting in a remainder of 700.
Use 7 as the next digit of our solution. 
Result so far: 61969.3677
Subtracting 6300 from 7000 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 61969.3677 with a balance of 0.007.
