79251939 ÷ 102 
We want to divide 79251939 by 102.

Moving on to step 1:
7 divided by 102 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 102

Advancing to step 2:
When dividing 79 by 102, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 102

Moving on to step 3:
The number 102 fits into 792 7 times, leaving a remainder of 78.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 714 from 792 to get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 102

Let's proceed to step 4:
102 goes into 785 7 times with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 714 from 785 leaves us with 71.
Fetch the next digit (1) from the dividend, attach it to 71 and continue: 711 / 102

Going ahead to step 5:
711 divided by 102 is 6 with a remainder of 99.
Put 6 as the next digit of the answer. 
Result so far: 776.0
Subtract 612 from 711 to get 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 102

Advancing to step 6:
102 can be fit into 999 9 times, resulting in a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 7769.0
Subtracting 918 from 999 leaves us with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 102

On to step 7:
102 goes into 813 7 times with a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 77697.0
Subtract 714 from 813 to get 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 102

Going ahead to step 8:
102 goes into 999 9 times with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 776979.0
If we take 918 away from 999, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
102 can be fit into 810 7 times, resulting in a remainder of 96.
Use 7 as the next digit of our solution. 
Result so far: 776979.7
If we subtract 714 from 810, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
960 divided by 102 is 9 with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 776979.79
If we take 918 away from 960, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
102 can be fit into 420 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 776979.794
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
The number 102 fits into 120 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 776979.7941
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
When dividing 180 by 102, we get 1 with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 776979.79411
Deduct 102 from 180 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The quotient of the division is 776979.79411, and the remainder is 7.8e-05.
