Let's divide 80641820 by 949
We want to figure out the number of times 80641820 can be divided by 949.

Step 1:
If we divide 8 by 949, 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.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 949

Advancing to step 2:
80 divided by 949 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 949

Advancing to step 3:
When dividing 806 by 949, we get 0 with a remainder of 806.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 806, we get 806.
Include the next digit (4) from the dividend after 806, then repeat: 8064 / 949

Step 4:
If we divide 8064 by 949, we get 8 and a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7592 from 8064 to get 472.
Grab the next digit (1) from the dividend, add it to 472, then carry on: 4721 / 949

Moving on to step 5:
949 can be fit into 4721 4 times, resulting in a remainder of 925.
The next digit of our result is 4. 
Result so far: 84.0
If we take 3796 away from 4721, we end up with 925.
Take the next digit (8) from the dividend and append it to 925, then repeat: 9258 / 949

Step 6:
949 goes into 9258 9 times with a remainder of 717.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
If we take 8541 away from 9258, we end up with 717.
Take the next digit (2) from the dividend and append it to 717, then repeat: 7172 / 949

On to step 7:
When dividing 7172 by 949, we get 7 with a remainder of 529.
Write down 7 as next digit of the result. 
Result so far: 8497.0
If we take 6643 away from 7172, we end up with 529.
Include the next digit (0) from the dividend after 529, then repeat: 5290 / 949

Advancing to step 8:
5290 divided by 949 is 5 with a remainder of 545.
The next digit of our result is 5. 
Result so far: 84975.0
If we take 4745 away from 5290, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 9:
949 goes into 5450 5 times with a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 84975.5
Subtracting 4745 from 5450 leaves us with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Let's proceed to step 10:
949 can be fit into 7050 7 times, resulting in a remainder of 407.
Record the quotient 7 as the next digit in the result. 
Result so far: 84975.57
The remainder is 407 after subtracting 6643 from 7050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 11:
4070 divided by 949 is 4 with a remainder of 274.
Use 4 as the next digit of our solution. 
Result so far: 84975.574
If we subtract 3796 from 4070, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 12:
949 goes into 2740 2 times with a remainder of 842.
Put 2 as the next digit of the answer. 
Result so far: 84975.5742
If we take 1898 away from 2740, we end up with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Moving on to step 13:
8420 divided by 949 is 8 with a remainder of 828.
The number 8 becomes the next digit in our result. 
Result so far: 84975.57428
Deduct 7592 from 8420 and we're left with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Going ahead to step 14:
949 goes into 8280 8 times with a remainder of 688.
The next digit of our result is 8. 
Result so far: 84975.574288
Deduct 7592 from 8280 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

The final result is 84975.574288 with a remainder of 6.88e-05.
