We're dividing 98579151 by 857 
We want to figure out the number of times 98579151 can be divided by 857.

On to step 1:
If we divide 9 by 857, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 857

Step 2:
If we divide 98 by 857, we get 0 and a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 857

On to step 3:
857 goes into 985 1 times with a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 857 from 985 leaves us with 128.
Include the next digit (7) from the dividend after 128, then repeat: 1287 / 857

Going ahead to step 4:
1287 divided by 857 is 1 with a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 857 from 1287 leaves us with 430.
Append the next digit (9) from the dividend to 430 and continue with: 4309 / 857

On to step 5:
4309 divided by 857 is 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 115.0
Subtract 4285 from 4309 to get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 857

On to step 6:
When dividing 241 by 857, we get 0 with a remainder of 241.
Write down 0 as next digit of the result. 
Result so far: 1150.0
If we subtract 0 from 241, we get 241.
Include the next digit (5) from the dividend after 241, then repeat: 2415 / 857

Let's proceed to step 7:
857 goes into 2415 2 times with a remainder of 701.
Put 2 as the next digit of the answer. 
Result so far: 11502.0
Deduct 1714 from 2415 and we're left with 701.
Fetch the next digit (1) from the dividend, attach it to 701 and continue: 7011 / 857

Step 8:
If we divide 7011 by 857, we get 8 and a remainder of 155.
Record the quotient 8 as the next digit in the result. 
Result so far: 115028.0
Subtracting 6856 from 7011 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
857 goes into 1550 1 times with a remainder of 693.
The number 1 becomes the next digit in our result. 
Result so far: 115028.1
If we take 857 away from 1550, we end up with 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Step 10:
857 can be fit into 6930 8 times, resulting in a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 115028.18
Subtract 6856 from 6930 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
740 divided by 857 is 0 with a remainder of 740.
Use 0 as the next digit of our solution. 
Result so far: 115028.18
If we subtract 0 from 740, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 12:
857 can be fit into 7400 8 times, resulting in a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 115028.1808
Subtract 6856 from 7400 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Let's proceed to step 13:
The number 857 fits into 5440 6 times, leaving a remainder of 298.
Record the quotient 6 as the next digit in the result. 
Result so far: 115028.18086
Subtract 5142 from 5440 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 14:
When dividing 2980 by 857, we get 3 with a remainder of 409.
The next digit of our result is 3. 
Result so far: 115028.180863
Deduct 2571 from 2980 and we're left with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 15:
The number 857 fits into 4090 4 times, leaving a remainder of 662.
Use 4 as the next digit of our solution. 
Result so far: 115028.1808634
If we take 3428 away from 4090, we end up with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Step 16:
857 can be fit into 6620 7 times, resulting in a remainder of 621.
Record the quotient 7 as the next digit in the result. 
Result so far: 115028.18086347
Deduct 5999 from 6620 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

After the division, we end up with 115028.18086347 and a remainder of 6.21e-07.
