We look at the division of 81939820 by 958 
We're looking to find how many times 958 goes into 81939820.

Step 1:
If we divide 8 by 958, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 958

On to step 2:
When dividing 81 by 958, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 958

Advancing to step 3:
The number 958 fits into 819 0 times, leaving a remainder of 819.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 819, we end up with 819.
Include the next digit (3) from the dividend after 819, then repeat: 8193 / 958

Let's proceed to step 4:
If we divide 8193 by 958, we get 8 and a remainder of 529.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7664 from 8193, we get 529.
Grab the next digit (9) from the dividend, add it to 529, then carry on: 5299 / 958

Advancing to step 5:
5299 divided by 958 is 5 with a remainder of 509.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we subtract 4790 from 5299, we get 509.
Take the next digit (8) from the dividend and append it to 509, then repeat: 5098 / 958

Going ahead to step 6:
If we divide 5098 by 958, we get 5 and a remainder of 308.
Record the quotient 5 as the next digit in the result. 
Result so far: 855.0
Subtract 4790 from 5098 to get 308.
Fetch the next digit (2) from the dividend, attach it to 308 and continue: 3082 / 958

Going ahead to step 7:
When dividing 3082 by 958, we get 3 with a remainder of 208.
Record the quotient 3 as the next digit in the result. 
Result so far: 8553.0
If we take 2874 away from 3082, we end up with 208.
Fetch the next digit (0) from the dividend, attach it to 208 and continue: 2080 / 958

Going ahead to step 8:
When dividing 2080 by 958, we get 2 with a remainder of 164.
Put 2 as the next digit of the answer. 
Result so far: 85532.0
Deduct 1916 from 2080 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 9:
958 can be fit into 1640 1 times, resulting in a remainder of 682.
The number 1 becomes the next digit in our result. 
Result so far: 85532.1
If we subtract 958 from 1640, we get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Going ahead to step 10:
The number 958 fits into 6820 7 times, leaving a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 85532.17
Subtracting 6706 from 6820 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 11:
When dividing 1140 by 958, we get 1 with a remainder of 182.
Write down 1 as next digit of the result. 
Result so far: 85532.171
Subtracting 958 from 1140 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 12:
The number 958 fits into 1820 1 times, leaving a remainder of 862.
Record the quotient 1 as the next digit in the result. 
Result so far: 85532.1711
The remainder is 862 after subtracting 958 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

The quotient of the division is 85532.1711, and the remainder is 0.00862.
