Let's divide 66021997 by 837
Let's see how many times 837 fits into 66021997.

On to step 1:
When dividing 6 by 837, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 837

Going ahead to step 2:
The number 837 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 837

Step 3:
837 can be fit into 660 0 times, resulting in a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 660 leaves us with 660.
Append the next digit (2) from the dividend to 660 and continue with: 6602 / 837

Let's proceed to step 4:
The number 837 fits into 6602 7 times, leaving a remainder of 743.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 5859 from 6602 to get 743.
Take the next digit (1) from the dividend and append it to 743, then repeat: 7431 / 837

Let's proceed to step 5:
If we divide 7431 by 837, we get 8 and a remainder of 735.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 6696 from 7431, we get 735.
Bring next digit (9) of the dividend behind the 735 and repeat the process: 7359 / 837

Advancing to step 6:
If we divide 7359 by 837, we get 8 and a remainder of 663.
Write down 8 as next digit of the result. 
Result so far: 788.0
If we subtract 6696 from 7359, we get 663.
Bring next digit (9) of the dividend behind the 663 and repeat the process: 6639 / 837

On to step 7:
837 can be fit into 6639 7 times, resulting in a remainder of 780.
Use 7 as the next digit of our solution. 
Result so far: 7887.0
Subtracting 5859 from 6639 leaves us with 780.
Include the next digit (7) from the dividend after 780, then repeat: 7807 / 837

Moving on to step 8:
837 goes into 7807 9 times with a remainder of 274.
Write down 9 as next digit of the result. 
Result so far: 78879.0
If we take 7533 away from 7807, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
If we divide 2740 by 837, we get 3 and a remainder of 229.
The next digit of our result is 3. 
Result so far: 78879.3
If we take 2511 away from 2740, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 10:
If we divide 2290 by 837, we get 2 and a remainder of 616.
Write down 2 as next digit of the result. 
Result so far: 78879.32
Subtracting 1674 from 2290 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 11:
837 can be fit into 6160 7 times, resulting in a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 78879.327
If we subtract 5859 from 6160, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 12:
If we divide 3010 by 837, we get 3 and a remainder of 499.
Use 3 as the next digit of our solution. 
Result so far: 78879.3273
If we take 2511 away from 3010, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

On to step 13:
837 can be fit into 4990 5 times, resulting in a remainder of 805.
Record the quotient 5 as the next digit in the result. 
Result so far: 78879.32735
If we subtract 4185 from 4990, we get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 14:
The number 837 fits into 8050 9 times, leaving a remainder of 517.
The next digit of our result is 9. 
Result so far: 78879.327359
Subtract 7533 from 8050 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Advancing to step 15:
When dividing 5170 by 837, we get 6 with a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 78879.3273596
Subtracting 5022 from 5170 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 16:
1480 divided by 837 is 1 with a remainder of 643.
The next digit of our result is 1. 
Result so far: 78879.32735961
The remainder is 643 after subtracting 837 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

The final outcome is 78879.32735961, with a leftover of 6.43e-07.
