66428091 divided by 826 
We want to divide 66428091 by 826.

Moving on to step 1:
6 divided by 826 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 826

Step 2:
If we divide 66 by 826, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 826

On to step 3:
When dividing 664 by 826, we get 0 with a remainder of 664.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 664 and we're left with 664.
Bring next digit (2) of the dividend behind the 664 and repeat the process: 6642 / 826

Advancing to step 4:
826 goes into 6642 8 times with a remainder of 34.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6608 from 6642 and we're left with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 826

On to step 5:
348 divided by 826 is 0 with a remainder of 348.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Deduct 0 from 348 and we're left with 348.
Append the next digit (0) from the dividend to 348 and continue with: 3480 / 826

Moving on to step 6:
The number 826 fits into 3480 4 times, leaving a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 804.0
If we subtract 3304 from 3480, we get 176.
Take the next digit (9) from the dividend and append it to 176, then repeat: 1769 / 826

Let's proceed to step 7:
When dividing 1769 by 826, we get 2 with a remainder of 117.
Record the quotient 2 as the next digit in the result. 
Result so far: 8042.0
The remainder is 117 after subtracting 1652 from 1769.
Fetch the next digit (1) from the dividend, attach it to 117 and continue: 1171 / 826

Let's proceed to step 8:
When dividing 1171 by 826, we get 1 with a remainder of 345.
The next digit of our result is 1. 
Result so far: 80421.0
The remainder is 345 after subtracting 826 from 1171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 9:
826 can be fit into 3450 4 times, resulting in a remainder of 146.
The next digit of our result is 4. 
Result so far: 80421.4
The remainder is 146 after subtracting 3304 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
If we divide 1460 by 826, we get 1 and a remainder of 634.
Put 1 as the next digit of the answer. 
Result so far: 80421.41
Deduct 826 from 1460 and we're left with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Step 11:
826 can be fit into 6340 7 times, resulting in a remainder of 558.
Write down 7 as next digit of the result. 
Result so far: 80421.417
Deduct 5782 from 6340 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Step 12:
If we divide 5580 by 826, we get 6 and a remainder of 624.
Use 6 as the next digit of our solution. 
Result so far: 80421.4176
If we take 4956 away from 5580, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 13:
826 can be fit into 6240 7 times, resulting in a remainder of 458.
Put 7 as the next digit of the answer. 
Result so far: 80421.41767
If we take 5782 away from 6240, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 14:
When dividing 4580 by 826, we get 5 with a remainder of 450.
The next digit of our result is 5. 
Result so far: 80421.417675
The remainder is 450 after subtracting 4130 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
When dividing 4500 by 826, we get 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 80421.4176755
If we take 4130 away from 4500, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final result is 80421.4176755 with a remainder of 3.7e-06.
