We're dividing 99868858 by 83 
We want to figure out the number of times 99868858 can be divided by 83.

Step 1:
If we divide 9 by 83, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 83

Moving on to step 2:
83 goes into 99 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 83 from 99 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 83

Let's proceed to step 3:
83 goes into 168 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 166 away from 168, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 83

Step 4:
26 divided by 83 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 83

Let's proceed to step 5:
If we divide 268 by 83, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 1203.0
The remainder is 19 after subtracting 249 from 268.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 83

Step 6:
83 can be fit into 198 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12032.0
Deduct 166 from 198 and we're left with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 83

Step 7:
83 goes into 325 3 times with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 120323.0
If we subtract 249 from 325, we get 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 83

Let's proceed to step 8:
If we divide 768 by 83, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1203239.0
Subtract 747 from 768 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
The number 83 fits into 210 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 1203239.2
Subtracting 166 from 210 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
The number 83 fits into 440 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1203239.25
If we take 415 away from 440, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
83 goes into 250 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1203239.253
If we subtract 249 from 250, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
If we divide 10 by 83, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1203239.253
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 83, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1203239.25301
Deduct 83 from 100 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
83 goes into 170 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1203239.253012
Deduct 166 from 170 and we're left with 4.
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 15:
40 divided by 83 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1203239.253012
Subtract 0 from 40 to get 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 16:
83 goes into 400 4 times with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 1203239.25301204
The remainder is 68 after subtracting 332 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 1203239.25301204, with a leftover of 6.8e-08.
