Let's divide 77900670 by 102
We want to divide 77900670 by 102.

Moving on to step 1:
7 divided by 102 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 102

Advancing to step 2:
The number 102 fits into 77 0 times, leaving 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.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 102

On to step 3:
102 can be fit into 779 7 times, resulting in a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 714 from 779 and we're left with 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 102

Going ahead to step 4:
The number 102 fits into 650 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Deduct 612 from 650 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 102

Let's proceed to step 5:
102 can be fit into 380 3 times, resulting in a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 763.0
Subtract 306 from 380 to get 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 102

Moving on to step 6:
If we divide 746 by 102, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 7637.0
If we subtract 714 from 746, we get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 102

Advancing to step 7:
327 divided by 102 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 76373.0
The remainder is 21 after subtracting 306 from 327.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 102

Moving on to step 8:
The number 102 fits into 210 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 763732.0
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 102 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 763732.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
102 goes into 600 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 763732.05
Subtract 510 from 600 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 11:
If we divide 900 by 102, we get 8 and a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 763732.058
Subtract 816 from 900 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
840 divided by 102 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 763732.0588
If we subtract 816 from 840, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 763732.0588, with a leftover of 0.00024.
