We divide 21852013 by 155
We want to figure out the number of times 21852013 can be divided by 155.

Moving on to step 1:
2 divided by 155 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 155

Advancing to step 2:
If we divide 21 by 155, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 155

On to step 3:
155 can be fit into 218 1 times, resulting in a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 155 away from 218, we end up with 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 155

Going ahead to step 4:
When dividing 635 by 155, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 620 from 635 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 155

Let's proceed to step 5:
If we divide 152 by 155, we get 0 and a remainder of 152.
Write down 0 as next digit of the result. 
Result so far: 140.0
Deduct 0 from 152 and we're left with 152.
Grab the next digit (0) from the dividend, add it to 152, then carry on: 1520 / 155

Moving on to step 6:
The number 155 fits into 1520 9 times, leaving a remainder of 125.
The number 9 becomes the next digit in our result. 
Result so far: 1409.0
If we subtract 1395 from 1520, we get 125.
Fetch the next digit (1) from the dividend, attach it to 125 and continue: 1251 / 155

Moving on to step 7:
If we divide 1251 by 155, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 14098.0
Subtract 1240 from 1251 to get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 155

Advancing to step 8:
155 goes into 113 0 times with a remainder of 113.
Record the quotient 0 as the next digit in the result. 
Result so far: 140980.0
If we subtract 0 from 113, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
155 can be fit into 1130 7 times, resulting in a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 140980.7
Deduct 1085 from 1130 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
155 can be fit into 450 2 times, resulting in a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 140980.72
Deduct 310 from 450 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
155 goes into 1400 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 140980.729
Subtract 1395 from 1400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
155 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 140980.729
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
If we divide 500 by 155, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 140980.72903
If we take 465 away from 500, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
350 divided by 155 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 140980.729032
Subtracting 310 from 350 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
The number 155 fits into 400 2 times, leaving a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 140980.7290322
Deduct 310 from 400 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final result is 140980.7290322 with a remainder of 9e-07.
