We're dividing 21758419 by 151 
We want to divide 21758419 by 151.

Let's proceed to step 1:
The number 151 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 151

On to step 2:
21 divided by 151 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 151

Going ahead to step 3:
The number 151 fits into 217 1 times, leaving a remainder of 66.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 151 from 217 to get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 151

Moving on to step 4:
The number 151 fits into 665 4 times, leaving a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 604 from 665, we get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 151

Moving on to step 5:
When dividing 618 by 151, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 144.0
The remainder is 14 after subtracting 604 from 618.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 151

Advancing to step 6:
When dividing 144 by 151, we get 0 with a remainder of 144.
Write down 0 as next digit of the result. 
Result so far: 1440.0
The remainder is 144 after subtracting 0 from 144.
Take the next digit (1) from the dividend and append it to 144, then repeat: 1441 / 151

Going ahead to step 7:
151 goes into 1441 9 times with a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 14409.0
Subtracting 1359 from 1441 leaves us with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 151

Going ahead to step 8:
151 goes into 829 5 times with a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 144095.0
Subtract 755 from 829 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
The number 151 fits into 740 4 times, leaving a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 144095.4
If we take 604 away from 740, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
151 can be fit into 1360 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 144095.49
If we take 1359 away from 1360, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
151 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 144095.49
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
151 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 144095.49
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 144095.49 with a remainder of 0.001.
