99717904 ÷ 859 
We're looking to find how many times 859 goes into 99717904.

On to step 1:
859 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 859

On to step 2:
When dividing 99 by 859, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (7) from the dividend, add it to 99, then carry on: 997 / 859

Step 3:
If we divide 997 by 859, we get 1 and a remainder of 138.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 859 from 997 to get 138.
Fetch the next digit (1) from the dividend, attach it to 138 and continue: 1381 / 859

On to step 4:
The number 859 fits into 1381 1 times, leaving a remainder of 522.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 859 away from 1381, we end up with 522.
Append the next digit (7) from the dividend to 522 and continue with: 5227 / 859

On to step 5:
859 can be fit into 5227 6 times, resulting in a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtract 5154 from 5227 to get 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 859

Step 6:
859 can be fit into 739 0 times, resulting in a remainder of 739.
The next digit of our result is 0. 
Result so far: 1160.0
The remainder is 739 after subtracting 0 from 739.
Bring next digit (0) of the dividend behind the 739 and repeat the process: 7390 / 859

On to step 7:
When dividing 7390 by 859, we get 8 with a remainder of 518.
Put 8 as the next digit of the answer. 
Result so far: 11608.0
Subtracting 6872 from 7390 leaves us with 518.
Include the next digit (4) from the dividend after 518, then repeat: 5184 / 859

Going ahead to step 8:
The number 859 fits into 5184 6 times, leaving a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 116086.0
Subtract 5154 from 5184 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
859 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 116086.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
If we divide 3000 by 859, we get 3 and a remainder of 423.
Write down 3 as next digit of the result. 
Result so far: 116086.03
The remainder is 423 after subtracting 2577 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 11:
The number 859 fits into 4230 4 times, leaving a remainder of 794.
The next digit of our result is 4. 
Result so far: 116086.034
Deduct 3436 from 4230 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Let's proceed to step 12:
When dividing 7940 by 859, we get 9 with a remainder of 209.
Write down 9 as next digit of the result. 
Result so far: 116086.0349
Subtract 7731 from 7940 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 13:
859 goes into 2090 2 times with a remainder of 372.
Write down 2 as next digit of the result. 
Result so far: 116086.03492
Deduct 1718 from 2090 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 14:
When dividing 3720 by 859, we get 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 116086.034924
The remainder is 284 after subtracting 3436 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 15:
859 can be fit into 2840 3 times, resulting in a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 116086.0349243
Deduct 2577 from 2840 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 16:
When dividing 2630 by 859, we get 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 116086.03492433
The remainder is 53 after subtracting 2577 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 116086.03492433, with a leftover of 5.3e-08.
