We divide 79210978 by 910
We want to figure out the number of times 79210978 can be divided by 910.

Moving on to step 1:
If we divide 7 by 910, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 910

Step 2:
79 divided by 910 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 910

Let's proceed to step 3:
When dividing 792 by 910, we get 0 with a remainder of 792.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 792, we end up with 792.
Fetch the next digit (1) from the dividend, attach it to 792 and continue: 7921 / 910

Let's proceed to step 4:
The number 910 fits into 7921 8 times, leaving a remainder of 641.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7280 away from 7921, we end up with 641.
Grab the next digit (0) from the dividend, add it to 641, then carry on: 6410 / 910

Step 5:
910 can be fit into 6410 7 times, resulting in a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we subtract 6370 from 6410, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 910

Moving on to step 6:
If we divide 409 by 910, we get 0 and a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 870.0
Deduct 0 from 409 and we're left with 409.
Grab the next digit (7) from the dividend, add it to 409, then carry on: 4097 / 910

Advancing to step 7:
910 goes into 4097 4 times with a remainder of 457.
The next digit of our result is 4. 
Result so far: 8704.0
If we take 3640 away from 4097, we end up with 457.
Fetch the next digit (8) from the dividend, attach it to 457 and continue: 4578 / 910

Advancing to step 8:
910 can be fit into 4578 5 times, resulting in a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 87045.0
Deduct 4550 from 4578 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
280 divided by 910 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 87045.0
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
When dividing 2800 by 910, we get 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 87045.03
If we subtract 2730 from 2800, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
If we divide 700 by 910, we get 0 and a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 87045.03
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 12:
If we divide 7000 by 910, we get 7 and a remainder of 630.
The next digit of our result is 7. 
Result so far: 87045.0307
If we take 6370 away from 7000, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 13:
If we divide 6300 by 910, we get 6 and a remainder of 840.
Write down 6 as next digit of the result. 
Result so far: 87045.03076
If we subtract 5460 from 6300, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 14:
If we divide 8400 by 910, we get 9 and a remainder of 210.
The next digit of our result is 9. 
Result so far: 87045.030769
Subtracting 8190 from 8400 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 15:
The number 910 fits into 2100 2 times, leaving a remainder of 280.
The next digit of our result is 2. 
Result so far: 87045.0307692
If we take 1820 away from 2100, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
910 can be fit into 2800 3 times, resulting in a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 87045.03076923
Subtract 2730 from 2800 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 87045.03076923 with a balance of 7e-08.
