21769458 ÷ 152 
Our goal is to divide 21769458 by 152.

Let's proceed to step 1:
152 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 152

Moving on to step 2:
152 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 152

Advancing to step 3:
If we divide 217 by 152, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 152 away from 217, we end up with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 152

Advancing to step 4:
If we divide 656 by 152, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 608 away from 656, we end up with 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 152

On to step 5:
152 goes into 489 3 times with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we take 456 away from 489, we end up with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 152

Moving on to step 6:
152 goes into 334 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 1432.0
Subtract 304 from 334 to get 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 152

Step 7:
152 goes into 305 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 14322.0
If we subtract 304 from 305, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 152

Advancing to step 8:
18 divided by 152 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 143220.0
Subtracting 0 from 18 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
If we divide 180 by 152, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 143220.1
Subtracting 152 from 180 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 152 is 1 with a remainder of 128.
Use 1 as the next digit of our solution. 
Result so far: 143220.11
Subtract 152 from 280 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 143220.11 and a remainder of 0.128.
