We're dividing 55512889 by 872 
Our goal is to divide 55512889 by 872.

Advancing to step 1:
If we divide 5 by 872, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 872

Advancing to step 2:
55 divided by 872 is 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 872

Step 3:
555 divided by 872 is 0 with a remainder of 555.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 555, we end up with 555.
Bring next digit (1) of the dividend behind the 555 and repeat the process: 5551 / 872

Going ahead to step 4:
872 goes into 5551 6 times with a remainder of 319.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 5232 away from 5551, we end up with 319.
Grab the next digit (2) from the dividend, add it to 319, then carry on: 3192 / 872

On to step 5:
872 goes into 3192 3 times with a remainder of 576.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 2616 from 3192 to get 576.
Grab the next digit (8) from the dividend, add it to 576, then carry on: 5768 / 872

Advancing to step 6:
5768 divided by 872 is 6 with a remainder of 536.
Record the quotient 6 as the next digit in the result. 
Result so far: 636.0
Deduct 5232 from 5768 and we're left with 536.
Grab the next digit (8) from the dividend, add it to 536, then carry on: 5368 / 872

Moving on to step 7:
The number 872 fits into 5368 6 times, leaving a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 6366.0
Subtract 5232 from 5368 to get 136.
Take the next digit (9) from the dividend and append it to 136, then repeat: 1369 / 872

Moving on to step 8:
1369 divided by 872 is 1 with a remainder of 497.
Use 1 as the next digit of our solution. 
Result so far: 63661.0
If we subtract 872 from 1369, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Let's proceed to step 9:
4970 divided by 872 is 5 with a remainder of 610.
Use 5 as the next digit of our solution. 
Result so far: 63661.5
If we take 4360 away from 4970, we end up 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.

On to step 10:
872 goes into 6100 6 times with a remainder of 868.
Put 6 as the next digit of the answer. 
Result so far: 63661.56
Deduct 5232 from 6100 and we're left with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

On to step 11:
If we divide 8680 by 872, we get 9 and a remainder of 832.
Write down 9 as next digit of the result. 
Result so far: 63661.569
Subtract 7848 from 8680 to get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Advancing to step 12:
872 can be fit into 8320 9 times, resulting in a remainder of 472.
Use 9 as the next digit of our solution. 
Result so far: 63661.5699
Subtract 7848 from 8320 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final outcome is 63661.5699, with a leftover of 0.00472.
