64901644 ÷ 149 
Our goal is to divide 64901644 by 149.

On to step 1:
If we divide 6 by 149, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 149

Let's proceed to step 2:
If we divide 64 by 149, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 149

Advancing to step 3:
The number 149 fits into 649 4 times, leaving a remainder of 53.
The next digit of our result is 4. 
Result so far: 4.0
If we take 596 away from 649, we end up with 53.
Fetch the next digit (0) from the dividend, attach it to 53 and continue: 530 / 149

Moving on to step 4:
If we divide 530 by 149, we get 3 and a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 447 from 530 to get 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 149

Going ahead to step 5:
The number 149 fits into 831 5 times, leaving a remainder of 86.
The next digit of our result is 5. 
Result so far: 435.0
If we take 745 away from 831, we end up with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 149

On to step 6:
When dividing 866 by 149, we get 5 with a remainder of 121.
The next digit of our result is 5. 
Result so far: 4355.0
Deduct 745 from 866 and we're left with 121.
Bring next digit (4) of the dividend behind the 121 and repeat the process: 1214 / 149

Going ahead to step 7:
149 can be fit into 1214 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 43558.0
Subtract 1192 from 1214 to get 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 149

Advancing to step 8:
149 goes into 224 1 times with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 435581.0
Subtracting 149 from 224 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
750 divided by 149 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 435581.5
Deduct 745 from 750 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 149 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 435581.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
149 can be fit into 500 3 times, resulting in a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 435581.503
If we subtract 447 from 500, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
The number 149 fits into 530 3 times, leaving a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 435581.5033
The remainder is 83 after subtracting 447 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Our division results in 435581.5033 with a remaining 0.00083.
