85129601 ÷ 579 
We're looking to find how many times 579 goes into 85129601.

Step 1:
When dividing 8 by 579, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 579

Advancing to step 2:
579 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 579

Let's proceed to step 3:
When dividing 851 by 579, we get 1 with a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 579 from 851, we get 272.
Append the next digit (2) from the dividend to 272 and continue with: 2722 / 579

Advancing to step 4:
579 goes into 2722 4 times with a remainder of 406.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 2316 from 2722 and we're left with 406.
Append the next digit (9) from the dividend to 406 and continue with: 4069 / 579

Step 5:
If we divide 4069 by 579, we get 7 and a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we take 4053 away from 4069, we end up with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 579

Let's proceed to step 6:
579 can be fit into 166 0 times, resulting in a remainder of 166.
Write down 0 as next digit of the result. 
Result so far: 1470.0
If we subtract 0 from 166, we get 166.
Bring next digit (0) of the dividend behind the 166 and repeat the process: 1660 / 579

Step 7:
579 goes into 1660 2 times with a remainder of 502.
The next digit of our result is 2. 
Result so far: 14702.0
If we subtract 1158 from 1660, we get 502.
Take the next digit (1) from the dividend and append it to 502, then repeat: 5021 / 579

Step 8:
579 goes into 5021 8 times with a remainder of 389.
Use 8 as the next digit of our solution. 
Result so far: 147028.0
If we take 4632 away from 5021, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 9:
If we divide 3890 by 579, we get 6 and a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 147028.6
If we take 3474 away from 3890, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 10:
579 can be fit into 4160 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 147028.67
Subtracting 4053 from 4160 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 11:
579 goes into 1070 1 times with a remainder of 491.
Record the quotient 1 as the next digit in the result. 
Result so far: 147028.671
Deduct 579 from 1070 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 12:
4910 divided by 579 is 8 with a remainder of 278.
Record the quotient 8 as the next digit in the result. 
Result so far: 147028.6718
Subtracting 4632 from 4910 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 13:
579 can be fit into 2780 4 times, resulting in a remainder of 464.
Use 4 as the next digit of our solution. 
Result so far: 147028.67184
If we subtract 2316 from 2780, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 14:
If we divide 4640 by 579, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 147028.671848
Deduct 4632 from 4640 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
80 divided by 579 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 147028.671848
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
If we divide 800 by 579, we get 1 and a remainder of 221.
Record the quotient 1 as the next digit in the result. 
Result so far: 147028.67184801
Deduct 579 from 800 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

After the division, we end up with 147028.67184801 and a remainder of 2.21e-07.
