We're dividing 64646338 by 149 
We want to divide 64646338 by 149.

Step 1:
When dividing 6 by 149, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 149

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
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (6) from the dividend, attach it to 64 and continue: 646 / 149

Step 3:
If we divide 646 by 149, we get 4 and a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 596 from 646, we get 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 149

Step 4:
504 divided by 149 is 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 447 from 504 and we're left with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 149

Advancing to step 5:
If we divide 576 by 149, we get 3 and a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 433.0
Deduct 447 from 576 and we're left with 129.
Append the next digit (3) from the dividend to 129 and continue with: 1293 / 149

Going ahead to step 6:
The number 149 fits into 1293 8 times, leaving a remainder of 101.
Record the quotient 8 as the next digit in the result. 
Result so far: 4338.0
Subtract 1192 from 1293 to get 101.
Take the next digit (3) from the dividend and append it to 101, then repeat: 1013 / 149

Moving on to step 7:
The number 149 fits into 1013 6 times, leaving a remainder of 119.
Put 6 as the next digit of the answer. 
Result so far: 43386.0
If we subtract 894 from 1013, we get 119.
Bring next digit (8) of the dividend behind the 119 and repeat the process: 1198 / 149

On to step 8:
The number 149 fits into 1198 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 433868.0
If we subtract 1192 from 1198, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
149 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 433868.0
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.

On to step 10:
When dividing 600 by 149, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 433868.04
The remainder is 4 after subtracting 596 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
40 divided by 149 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 433868.04
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 149, we get 2 with a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 433868.0402
Subtracting 298 from 400 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 13:
1020 divided by 149 is 6 with a remainder of 126.
The next digit of our result is 6. 
Result so far: 433868.04026
Deduct 894 from 1020 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 14:
The number 149 fits into 1260 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 433868.040268
If we take 1192 away from 1260, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 15:
149 goes into 680 4 times with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 433868.0402684
The remainder is 84 after subtracting 596 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 16:
149 goes into 840 5 times with a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 433868.04026845
Subtract 745 from 840 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final outcome is 433868.04026845, with a leftover of 9.5e-08.
