We look at the division of 77762170 by 389 
We're looking to find how many times 389 goes into 77762170.

Let's proceed to step 1:
389 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 389

Going ahead to step 2:
When dividing 77 by 389, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 389

Going ahead to step 3:
The number 389 fits into 777 1 times, leaving a remainder of 388.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 389 from 777 leaves us with 388.
Append the next digit (6) from the dividend to 388 and continue with: 3886 / 389

Let's proceed to step 4:
3886 divided by 389 is 9 with a remainder of 385.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3501 from 3886, we get 385.
Append the next digit (2) from the dividend to 385 and continue with: 3852 / 389

On to step 5:
When dividing 3852 by 389, we get 9 with a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 199.0
If we take 3501 away from 3852, we end up with 351.
Fetch the next digit (1) from the dividend, attach it to 351 and continue: 3511 / 389

Advancing to step 6:
389 goes into 3511 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 1999.0
Subtracting 3501 from 3511 leaves us with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 389

Advancing to step 7:
The number 389 fits into 107 0 times, leaving a remainder of 107.
Use 0 as the next digit of our solution. 
Result so far: 19990.0
If we subtract 0 from 107, we get 107.
Take the next digit (0) from the dividend and append it to 107, then repeat: 1070 / 389

Step 8:
The number 389 fits into 1070 2 times, leaving a remainder of 292.
The number 2 becomes the next digit in our result. 
Result so far: 199902.0
The remainder is 292 after subtracting 778 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
The number 389 fits into 2920 7 times, leaving a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 199902.7
If we take 2723 away from 2920, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 10:
1970 divided by 389 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 199902.75
Subtracting 1945 from 1970 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
389 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 199902.75
If we subtract 0 from 250, 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 12:
If we divide 2500 by 389, we get 6 and a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 199902.7506
Deduct 2334 from 2500 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 13:
1660 divided by 389 is 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 199902.75064
The remainder is 104 after subtracting 1556 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 14:
If we divide 1040 by 389, we get 2 and a remainder of 262.
Record the quotient 2 as the next digit in the result. 
Result so far: 199902.750642
Deduct 778 from 1040 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 15:
When dividing 2620 by 389, we get 6 with a remainder of 286.
The next digit of our result is 6. 
Result so far: 199902.7506426
Deduct 2334 from 2620 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 16:
389 can be fit into 2860 7 times, resulting in a remainder of 137.
Write down 7 as next digit of the result. 
Result so far: 199902.75064267
If we take 2723 away from 2860, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final result is 199902.75064267 with a remainder of 1.37e-07.
