53489311 ÷ 181 
We want to figure out the number of times 53489311 can be divided by 181.

Step 1:
5 divided by 181 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 181

Going ahead to step 2:
181 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 181

Going ahead to step 3:
When dividing 534 by 181, we get 2 with a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 362 from 534 and we're left with 172.
Grab the next digit (8) from the dividend, add it to 172, then carry on: 1728 / 181

On to step 4:
When dividing 1728 by 181, we get 9 with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 99 after subtracting 1629 from 1728.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 181

Advancing to step 5:
The number 181 fits into 999 5 times, leaving a remainder of 94.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Subtract 905 from 999 to get 94.
Append the next digit (3) from the dividend to 94 and continue with: 943 / 181

Let's proceed to step 6:
If we divide 943 by 181, we get 5 and a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 2955.0
Subtract 905 from 943 to get 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 181

Advancing to step 7:
The number 181 fits into 381 2 times, leaving a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 29552.0
Subtracting 362 from 381 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 181

Moving on to step 8:
181 can be fit into 191 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 295521.0
The remainder is 10 after subtracting 181 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 181 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 295521.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
When dividing 1000 by 181, we get 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 295521.05
Deduct 905 from 1000 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 11:
181 goes into 950 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 295521.055
The remainder is 45 after subtracting 905 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 295521.055, and the remainder is 0.0045.
