We look at the division of 64538579 by 749 
We're looking to find how many times 749 goes into 64538579.

Step 1:
When dividing 6 by 749, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 749

Moving on to step 2:
749 goes into 64 0 times with 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.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 749

On to step 3:
When dividing 645 by 749, we get 0 with a remainder of 645.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 645 and we're left with 645.
Include the next digit (3) from the dividend after 645, then repeat: 6453 / 749

Step 4:
749 can be fit into 6453 8 times, resulting in a remainder of 461.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 5992 from 6453 and we're left with 461.
Bring next digit (8) of the dividend behind the 461 and repeat the process: 4618 / 749

On to step 5:
If we divide 4618 by 749, we get 6 and a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
Deduct 4494 from 4618 and we're left with 124.
Bring next digit (5) of the dividend behind the 124 and repeat the process: 1245 / 749

Let's proceed to step 6:
749 can be fit into 1245 1 times, resulting in a remainder of 496.
Record the quotient 1 as the next digit in the result. 
Result so far: 861.0
The remainder is 496 after subtracting 749 from 1245.
Fetch the next digit (7) from the dividend, attach it to 496 and continue: 4967 / 749

Moving on to step 7:
749 can be fit into 4967 6 times, resulting in a remainder of 473.
Use 6 as the next digit of our solution. 
Result so far: 8616.0
If we subtract 4494 from 4967, we get 473.
Bring next digit (9) of the dividend behind the 473 and repeat the process: 4739 / 749

Advancing to step 8:
When dividing 4739 by 749, we get 6 with a remainder of 245.
Use 6 as the next digit of our solution. 
Result so far: 86166.0
Deduct 4494 from 4739 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 9:
749 goes into 2450 3 times with a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 86166.3
If we subtract 2247 from 2450, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 10:
749 goes into 2030 2 times with a remainder of 532.
The number 2 becomes the next digit in our result. 
Result so far: 86166.32
If we take 1498 away from 2030, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 11:
749 can be fit into 5320 7 times, resulting in a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 86166.327
Subtract 5243 from 5320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
The number 749 fits into 770 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 86166.3271
If we take 749 away from 770, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 13:
749 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 86166.3271
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
The number 749 fits into 2100 2 times, leaving a remainder of 602.
The next digit of our result is 2. 
Result so far: 86166.327102
If we take 1498 away from 2100, we end up with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

On to step 15:
If we divide 6020 by 749, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 86166.3271028
Deduct 5992 from 6020 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
749 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 86166.3271028
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 86166.3271028 and a remainder of 2.8e-07.
