We're dividing 66109745 by 774 
Let's see how many times 774 fits into 66109745.

Advancing to step 1:
774 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 774

Moving on to step 2:
If we divide 66 by 774, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 774

Let's proceed to step 3:
661 divided by 774 is 0 with a remainder of 661.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 661 after subtracting 0 from 661.
Bring next digit (0) of the dividend behind the 661 and repeat the process: 6610 / 774

Moving on to step 4:
6610 divided by 774 is 8 with a remainder of 418.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6192 from 6610 to get 418.
Grab the next digit (9) from the dividend, add it to 418, then carry on: 4189 / 774

Moving on to step 5:
The number 774 fits into 4189 5 times, leaving a remainder of 319.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 3870 from 4189 leaves us with 319.
Take the next digit (7) from the dividend and append it to 319, then repeat: 3197 / 774

Moving on to step 6:
If we divide 3197 by 774, we get 4 and a remainder of 101.
Record the quotient 4 as the next digit in the result. 
Result so far: 854.0
Subtracting 3096 from 3197 leaves us with 101.
Grab the next digit (4) from the dividend, add it to 101, then carry on: 1014 / 774

Let's proceed to step 7:
774 can be fit into 1014 1 times, resulting in a remainder of 240.
The next digit of our result is 1. 
Result so far: 8541.0
Subtract 774 from 1014 to get 240.
Fetch the next digit (5) from the dividend, attach it to 240 and continue: 2405 / 774

On to step 8:
If we divide 2405 by 774, we get 3 and a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 85413.0
If we subtract 2322 from 2405, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
If we divide 830 by 774, we get 1 and a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 85413.1
The remainder is 56 after subtracting 774 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
If we divide 560 by 774, we get 0 and a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 85413.1
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
The number 774 fits into 5600 7 times, leaving a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 85413.107
If we subtract 5418 from 5600, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 12:
When dividing 1820 by 774, we get 2 with a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 85413.1072
Deduct 1548 from 1820 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 13:
2720 divided by 774 is 3 with a remainder of 398.
The number 3 becomes the next digit in our result. 
Result so far: 85413.10723
If we take 2322 away from 2720, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 14:
3980 divided by 774 is 5 with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 85413.107235
Subtracting 3870 from 3980 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
774 can be fit into 1100 1 times, resulting in a remainder of 326.
Use 1 as the next digit of our solution. 
Result so far: 85413.1072351
Subtracting 774 from 1100 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 16:
774 goes into 3260 4 times with a remainder of 164.
Record the quotient 4 as the next digit in the result. 
Result so far: 85413.10723514
Subtracting 3096 from 3260 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 85413.10723514, with a leftover of 1.64e-07.
