81815754 ÷ 170 
Our goal is to divide 81815754 by 170.

Moving on to step 1:
170 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 170

Advancing to step 2:
When dividing 81 by 170, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 170

On to step 3:
The number 170 fits into 818 4 times, leaving a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 680 from 818 and we're left with 138.
Take the next digit (1) from the dividend and append it to 138, then repeat: 1381 / 170

Step 4:
170 goes into 1381 8 times with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtracting 1360 from 1381 leaves us with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 170

Going ahead to step 5:
If we divide 215 by 170, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 481.0
Subtracting 170 from 215 leaves us with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 170

Advancing to step 6:
If we divide 457 by 170, we get 2 and a remainder of 117.
The next digit of our result is 2. 
Result so far: 4812.0
If we take 340 away from 457, we end up with 117.
Include the next digit (5) from the dividend after 117, then repeat: 1175 / 170

On to step 7:
The number 170 fits into 1175 6 times, leaving a remainder of 155.
The number 6 becomes the next digit in our result. 
Result so far: 48126.0
If we take 1020 away from 1175, we end up with 155.
Grab the next digit (4) from the dividend, add it to 155, then carry on: 1554 / 170

Step 8:
If we divide 1554 by 170, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 481269.0
The remainder is 24 after subtracting 1530 from 1554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 170, we get 1 and a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 481269.1
The remainder is 70 after subtracting 170 from 240.
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:
170 goes into 700 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 481269.14
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 170 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 481269.141
Subtract 170 from 200 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.

On to step 12:
170 can be fit into 300 1 times, resulting in a remainder of 130.
Write down 1 as next digit of the result. 
Result so far: 481269.1411
Subtract 170 from 300 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 481269.1411 with a balance of 0.0013.
