81405630 ÷ 850 
We're looking to find how many times 850 goes into 81405630.

Advancing to step 1:
850 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 850

Let's proceed to step 2:
850 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 850

Moving on to step 3:
The number 850 fits into 814 0 times, leaving a remainder of 814.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 814 to get 814.
Take the next digit (0) from the dividend and append it to 814, then repeat: 8140 / 850

Step 4:
If we divide 8140 by 850, we get 9 and a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 490 after subtracting 7650 from 8140.
Grab the next digit (5) from the dividend, add it to 490, then carry on: 4905 / 850

Moving on to step 5:
The number 850 fits into 4905 5 times, leaving a remainder of 655.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 655 after subtracting 4250 from 4905.
Include the next digit (6) from the dividend after 655, then repeat: 6556 / 850

On to step 6:
850 can be fit into 6556 7 times, resulting in a remainder of 606.
Record the quotient 7 as the next digit in the result. 
Result so far: 957.0
Deduct 5950 from 6556 and we're left with 606.
Fetch the next digit (3) from the dividend, attach it to 606 and continue: 6063 / 850

On to step 7:
6063 divided by 850 is 7 with a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 9577.0
Deduct 5950 from 6063 and we're left with 113.
Take the next digit (0) from the dividend and append it to 113, then repeat: 1130 / 850

Step 8:
When dividing 1130 by 850, we get 1 with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 95771.0
Deduct 850 from 1130 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 9:
2800 divided by 850 is 3 with a remainder of 250.
Write down 3 as next digit of the result. 
Result so far: 95771.3
If we subtract 2550 from 2800, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
When dividing 2500 by 850, we get 2 with a remainder of 800.
Put 2 as the next digit of the answer. 
Result so far: 95771.32
Subtract 1700 from 2500 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 11:
8000 divided by 850 is 9 with a remainder of 350.
Use 9 as the next digit of our solution. 
Result so far: 95771.329
Subtracting 7650 from 8000 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 12:
3500 divided by 850 is 4 with a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 95771.3294
If we subtract 3400 from 3500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 13:
If we divide 1000 by 850, we get 1 and a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 95771.32941
If we take 850 away from 1000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
1500 divided by 850 is 1 with a remainder of 650.
Record the quotient 1 as the next digit in the result. 
Result so far: 95771.329411
If we subtract 850 from 1500, 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.

Our division results in 95771.329411 with a remaining 6.5e-05.
