21760990 ÷ 152 
We want to figure out the number of times 21760990 can be divided by 152.

Advancing to step 1:
When dividing 2 by 152, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 152

Moving on to step 2:
152 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 152

Going ahead to step 3:
217 divided by 152 is 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 152 from 217, we get 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 152

On to step 4:
If we divide 656 by 152, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 48 after subtracting 608 from 656.
Fetch the next digit (0) from the dividend, attach it to 48 and continue: 480 / 152

Moving on to step 5:
152 goes into 480 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtract 456 from 480 to get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 152

Going ahead to step 6:
249 divided by 152 is 1 with a remainder of 97.
The next digit of our result is 1. 
Result so far: 1431.0
Subtract 152 from 249 to get 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 152

Moving on to step 7:
152 goes into 979 6 times with a remainder of 67.
The next digit of our result is 6. 
Result so far: 14316.0
Subtract 912 from 979 to get 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 152

Going ahead to step 8:
670 divided by 152 is 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 143164.0
The remainder is 62 after subtracting 608 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
The number 152 fits into 620 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 143164.4
Deduct 608 from 620 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 152, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 143164.4
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
152 can be fit into 1200 7 times, resulting in a remainder of 136.
Put 7 as the next digit of the answer. 
Result so far: 143164.407
If we subtract 1064 from 1200, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
1360 divided by 152 is 8 with a remainder of 144.
The next digit of our result is 8. 
Result so far: 143164.4078
The remainder is 144 after subtracting 1216 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
If we divide 1440 by 152, we get 9 and a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 143164.40789
If we take 1368 away from 1440, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
720 divided by 152 is 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 143164.407894
If we subtract 608 from 720, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 15:
152 goes into 1120 7 times with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 143164.4078947
If we subtract 1064 from 1120, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 16:
If we divide 560 by 152, we get 3 and a remainder of 104.
Record the quotient 3 as the next digit in the result. 
Result so far: 143164.40789473
The remainder is 104 after subtracting 456 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 143164.40789473 and a remainder of 1.04e-07.
