81939005 ÷ 985 
We're looking to find how many times 985 goes into 81939005.

Let's proceed to step 1:
985 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 985

Going ahead to step 2:
The number 985 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 985

Let's proceed to step 3:
The number 985 fits into 819 0 times, leaving a remainder of 819.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 819 and we're left with 819.
Bring next digit (3) of the dividend behind the 819 and repeat the process: 8193 / 985

On to step 4:
If we divide 8193 by 985, we get 8 and a remainder of 313.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7880 from 8193 and we're left with 313.
Grab the next digit (9) from the dividend, add it to 313, then carry on: 3139 / 985

Advancing to step 5:
3139 divided by 985 is 3 with a remainder of 184.
The next digit of our result is 3. 
Result so far: 83.0
If we take 2955 away from 3139, we end up with 184.
Bring next digit (0) of the dividend behind the 184 and repeat the process: 1840 / 985

Step 6:
When dividing 1840 by 985, we get 1 with a remainder of 855.
The next digit of our result is 1. 
Result so far: 831.0
Deduct 985 from 1840 and we're left with 855.
Grab the next digit (0) from the dividend, add it to 855, then carry on: 8550 / 985

Let's proceed to step 7:
The number 985 fits into 8550 8 times, leaving a remainder of 670.
Use 8 as the next digit of our solution. 
Result so far: 8318.0
Deduct 7880 from 8550 and we're left with 670.
Take the next digit (5) from the dividend and append it to 670, then repeat: 6705 / 985

On to step 8:
If we divide 6705 by 985, we get 6 and a remainder of 795.
The next digit of our result is 6. 
Result so far: 83186.0
Subtract 5910 from 6705 to get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Step 9:
985 can be fit into 7950 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 83186.8
The remainder is 70 after subtracting 7880 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
When dividing 700 by 985, we get 0 with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 83186.8
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 11:
985 goes into 7000 7 times with a remainder of 105.
Put 7 as the next digit of the answer. 
Result so far: 83186.807
Deduct 6895 from 7000 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 12:
1050 divided by 985 is 1 with a remainder of 65.
The next digit of our result is 1. 
Result so far: 83186.8071
Deduct 985 from 1050 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
When dividing 650 by 985, we get 0 with a remainder of 650.
Use 0 as the next digit of our solution. 
Result so far: 83186.8071
If we subtract 0 from 650, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Advancing to step 14:
985 can be fit into 6500 6 times, resulting in a remainder of 590.
Use 6 as the next digit of our solution. 
Result so far: 83186.807106
Subtract 5910 from 6500 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 15:
985 can be fit into 5900 5 times, resulting in a remainder of 975.
The next digit of our result is 5. 
Result so far: 83186.8071065
Subtracting 4925 from 5900 leaves us with 975.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9750, and continue the process.

Moving on to step 16:
If we divide 9750 by 985, we get 9 and a remainder of 885.
The next digit of our result is 9. 
Result so far: 83186.80710659
Subtract 8865 from 9750 to get 885.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8850, and continue the process.

Our division results in 83186.80710659 with a remaining 8.85e-07.
