20452521 ÷ 151 
We want to figure out the number of times 20452521 can be divided by 151.

On to step 1:
2 divided by 151 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 151

Advancing to step 2:
151 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 151

Let's proceed to step 3:
The number 151 fits into 204 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 151 from 204 to get 53.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 151

Advancing to step 4:
151 goes into 535 3 times with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 453 from 535 to get 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 151

Going ahead to step 5:
151 can be fit into 822 5 times, resulting in a remainder of 67.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
The remainder is 67 after subtracting 755 from 822.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 151

Advancing to step 6:
151 can be fit into 675 4 times, resulting in a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 1354.0
Subtracting 604 from 675 leaves us with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 151

Advancing to step 7:
The number 151 fits into 712 4 times, leaving a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 13544.0
The remainder is 108 after subtracting 604 from 712.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 151

Step 8:
151 can be fit into 1081 7 times, resulting in a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 135447.0
The remainder is 24 after subtracting 1057 from 1081.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
240 divided by 151 is 1 with a remainder of 89.
The next digit of our result is 1. 
Result so far: 135447.1
The remainder is 89 after subtracting 151 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 10:
890 divided by 151 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 135447.15
Subtracting 755 from 890 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
151 can be fit into 1350 8 times, resulting in a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 135447.158
Subtract 1208 from 1350 to 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 12:
1420 divided by 151 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 135447.1589
Deduct 1359 from 1420 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
610 divided by 151 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 135447.15894
The remainder is 6 after subtracting 604 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
60 divided by 151 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 135447.15894
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.

Step 15:
151 goes into 600 3 times with a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 135447.1589403
Subtract 453 from 600 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 16:
151 can be fit into 1470 9 times, resulting in a remainder of 111.
The next digit of our result is 9. 
Result so far: 135447.15894039
If we take 1359 away from 1470, we end up 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.

Our division results in 135447.15894039 with a remaining 1.11e-07.
