We look at the division of 64446520 by 151 
We want to figure out the number of times 64446520 can be divided by 151.

Let's proceed to step 1:
6 divided by 151 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 151

On to step 2:
151 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 151

Advancing to step 3:
151 can be fit into 644 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 604 from 644 to get 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 151

Moving on to step 4:
404 divided by 151 is 2 with a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 302 away from 404, we end up with 102.
Bring next digit (6) of the dividend behind the 102 and repeat the process: 1026 / 151

Moving on to step 5:
The number 151 fits into 1026 6 times, leaving a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 426.0
Subtracting 906 from 1026 leaves us with 120.
Bring next digit (5) of the dividend behind the 120 and repeat the process: 1205 / 151

On to step 6:
The number 151 fits into 1205 7 times, leaving a remainder of 148.
Use 7 as the next digit of our solution. 
Result so far: 4267.0
Subtracting 1057 from 1205 leaves us with 148.
Grab the next digit (2) from the dividend, add it to 148, then carry on: 1482 / 151

Advancing to step 7:
151 goes into 1482 9 times with a remainder of 123.
Use 9 as the next digit of our solution. 
Result so far: 42679.0
Subtract 1359 from 1482 to get 123.
Append the next digit (0) from the dividend to 123 and continue with: 1230 / 151

On to step 8:
151 can be fit into 1230 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 426798.0
Deduct 1208 from 1230 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 151, we get 1 and a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 426798.1
Subtract 151 from 220 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
151 can be fit into 690 4 times, resulting in a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 426798.14
If we take 604 away from 690, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
151 can be fit into 860 5 times, resulting in a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 426798.145
Subtract 755 from 860 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 12:
When dividing 1050 by 151, we get 6 with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 426798.1456
Subtract 906 from 1050 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
151 can be fit into 1440 9 times, resulting in a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 426798.14569
If we subtract 1359 from 1440, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 14:
When dividing 810 by 151, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 426798.145695
Subtract 755 from 810 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 15:
151 can be fit into 550 3 times, resulting in a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 426798.1456953
Deduct 453 from 550 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 16:
151 goes into 970 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 426798.14569536
If we subtract 906 from 970, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 426798.14569536 with a remaining 6.4e-08.
