We divide 21551459 by 151
We want to figure out the number of times 21551459 can be divided by 151.

Step 1:
If we divide 2 by 151, we get 0 and 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 151

Moving on to step 2:
151 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 151

Let's proceed to step 3:
The number 151 fits into 215 1 times, leaving a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 151 from 215 leaves us with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 151

Let's proceed to step 4:
151 goes into 645 4 times with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 604 from 645 and we're left with 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 151

Advancing to step 5:
151 goes into 411 2 times with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we take 302 away from 411, we end up with 109.
Grab the next digit (4) from the dividend, add it to 109, then carry on: 1094 / 151

On to step 6:
1094 divided by 151 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1427.0
If we subtract 1057 from 1094, we get 37.
Fetch the next digit (5) from the dividend, attach it to 37 and continue: 375 / 151

Going ahead to step 7:
151 goes into 375 2 times with a remainder of 73.
The next digit of our result is 2. 
Result so far: 14272.0
If we subtract 302 from 375, we get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 151

Let's proceed to step 8:
151 goes into 739 4 times with a remainder of 135.
Write down 4 as next digit of the result. 
Result so far: 142724.0
Subtract 604 from 739 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 9:
If we divide 1350 by 151, we get 8 and a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 142724.8
If we subtract 1208 from 1350, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
If we divide 1420 by 151, we get 9 and a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 142724.89
The remainder is 61 after subtracting 1359 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
When dividing 610 by 151, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 142724.894
Subtracting 604 from 610 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 151 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 142724.894
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
If we divide 600 by 151, we get 3 and a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 142724.89403
Deduct 453 from 600 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 14:
1470 divided by 151 is 9 with a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 142724.894039
Subtracting 1359 from 1470 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 15:
If we divide 1110 by 151, we get 7 and a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 142724.8940397
Subtracting 1057 from 1110 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 16:
530 divided by 151 is 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 142724.89403973
Deduct 453 from 530 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The quotient of the division is 142724.89403973, and the remainder is 7.7e-08.
