We look at the division of 79279236 by 643 
Let's see how many times 643 fits into 79279236.

Let's proceed to step 1:
When dividing 7 by 643, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 643

Moving on to step 2:
When dividing 79 by 643, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 643

Step 3:
643 goes into 792 1 times with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 643 from 792 and we're left with 149.
Bring next digit (7) of the dividend behind the 149 and repeat the process: 1497 / 643

Let's proceed to step 4:
The number 643 fits into 1497 2 times, leaving a remainder of 211.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1286 from 1497 and we're left with 211.
Bring next digit (9) of the dividend behind the 211 and repeat the process: 2119 / 643

Going ahead to step 5:
If we divide 2119 by 643, we get 3 and a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtract 1929 from 2119 to get 190.
Include the next digit (2) from the dividend after 190, then repeat: 1902 / 643

Let's proceed to step 6:
If we divide 1902 by 643, we get 2 and a remainder of 616.
The number 2 becomes the next digit in our result. 
Result so far: 1232.0
Subtracting 1286 from 1902 leaves us with 616.
Take the next digit (3) from the dividend and append it to 616, then repeat: 6163 / 643

Going ahead to step 7:
If we divide 6163 by 643, we get 9 and a remainder of 376.
Record the quotient 9 as the next digit in the result. 
Result so far: 12329.0
Subtract 5787 from 6163 to get 376.
Grab the next digit (6) from the dividend, add it to 376, then carry on: 3766 / 643

Advancing to step 8:
When dividing 3766 by 643, we get 5 with a remainder of 551.
Put 5 as the next digit of the answer. 
Result so far: 123295.0
If we subtract 3215 from 3766, we get 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 9:
643 can be fit into 5510 8 times, resulting in a remainder of 366.
The next digit of our result is 8. 
Result so far: 123295.8
Subtracting 5144 from 5510 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 10:
The number 643 fits into 3660 5 times, leaving a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 123295.85
Deduct 3215 from 3660 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 11:
643 goes into 4450 6 times with a remainder of 592.
Use 6 as the next digit of our solution. 
Result so far: 123295.856
If we take 3858 away from 4450, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 12:
If we divide 5920 by 643, we get 9 and a remainder of 133.
Use 9 as the next digit of our solution. 
Result so far: 123295.8569
The remainder is 133 after subtracting 5787 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 13:
When dividing 1330 by 643, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 123295.85692
If we take 1286 away from 1330, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
643 goes into 440 0 times with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 123295.85692
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 15:
4400 divided by 643 is 6 with a remainder of 542.
The next digit of our result is 6. 
Result so far: 123295.8569206
If we subtract 3858 from 4400, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 16:
5420 divided by 643 is 8 with a remainder of 276.
The next digit of our result is 8. 
Result so far: 123295.85692068
Subtract 5144 from 5420 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

In conclusion, the division gives 123295.85692068 with a balance of 2.76e-07.
