We look at the division of 76389191 by 979 
Our goal is to divide 76389191 by 979.

Advancing to step 1:
When dividing 7 by 979, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 979

Moving on to step 2:
If we divide 76 by 979, we get 0 and a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Bring next digit (3) of the dividend behind the 76 and repeat the process: 763 / 979

Moving on to step 3:
If we divide 763 by 979, we get 0 and a remainder of 763.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 763 leaves us with 763.
Grab the next digit (8) from the dividend, add it to 763, then carry on: 7638 / 979

On to step 4:
When dividing 7638 by 979, we get 7 with a remainder of 785.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 6853 away from 7638, we end up with 785.
Bring next digit (9) of the dividend behind the 785 and repeat the process: 7859 / 979

On to step 5:
The number 979 fits into 7859 8 times, leaving a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we take 7832 away from 7859, we end up with 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 979

Going ahead to step 6:
271 divided by 979 is 0 with a remainder of 271.
Put 0 as the next digit of the answer. 
Result so far: 780.0
Deduct 0 from 271 and we're left with 271.
Bring next digit (9) of the dividend behind the 271 and repeat the process: 2719 / 979

Moving on to step 7:
If we divide 2719 by 979, we get 2 and a remainder of 761.
Use 2 as the next digit of our solution. 
Result so far: 7802.0
If we take 1958 away from 2719, we end up with 761.
Take the next digit (1) from the dividend and append it to 761, then repeat: 7611 / 979

Let's proceed to step 8:
979 can be fit into 7611 7 times, resulting in a remainder of 758.
Write down 7 as next digit of the result. 
Result so far: 78027.0
If we take 6853 away from 7611, we end up with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Moving on to step 9:
979 can be fit into 7580 7 times, resulting in a remainder of 727.
Record the quotient 7 as the next digit in the result. 
Result so far: 78027.7
If we take 6853 away from 7580, we end up with 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Going ahead to step 10:
If we divide 7270 by 979, we get 7 and a remainder of 417.
The next digit of our result is 7. 
Result so far: 78027.77
Subtract 6853 from 7270 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

In conclusion, the division gives 78027.77 with a balance of 0.417.
