We look at the division of 77884663 by 397 
Our goal is to divide 77884663 by 397.

Let's proceed to step 1:
397 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 397

Let's proceed to step 2:
77 divided by 397 is 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 397

On to step 3:
778 divided by 397 is 1 with a remainder of 381.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 397 away from 778, we end up with 381.
Grab the next digit (8) from the dividend, add it to 381, then carry on: 3818 / 397

Advancing to step 4:
If we divide 3818 by 397, we get 9 and a remainder of 245.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3573 from 3818 to get 245.
Take the next digit (4) from the dividend and append it to 245, then repeat: 2454 / 397

Let's proceed to step 5:
397 goes into 2454 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 196.0
The remainder is 72 after subtracting 2382 from 2454.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 397

On to step 6:
726 divided by 397 is 1 with a remainder of 329.
The number 1 becomes the next digit in our result. 
Result so far: 1961.0
Subtracting 397 from 726 leaves us with 329.
Bring next digit (6) of the dividend behind the 329 and repeat the process: 3296 / 397

Advancing to step 7:
When dividing 3296 by 397, we get 8 with a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 19618.0
Subtract 3176 from 3296 to get 120.
Append the next digit (3) from the dividend to 120 and continue with: 1203 / 397

Moving on to step 8:
If we divide 1203 by 397, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 196183.0
The remainder is 12 after subtracting 1191 from 1203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 397, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 196183.0
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
When dividing 1200 by 397, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 196183.03
Subtract 1191 from 1200 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
397 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 196183.03
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
397 goes into 900 2 times with a remainder of 106.
Put 2 as the next digit of the answer. 
Result so far: 196183.0302
Subtracting 794 from 900 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
If we divide 1060 by 397, we get 2 and a remainder of 266.
Put 2 as the next digit of the answer. 
Result so far: 196183.03022
Subtracting 794 from 1060 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The final outcome is 196183.03022, with a leftover of 0.000266.
