79450990 ÷ 821 
We're looking to find how many times 821 goes into 79450990.

Going ahead to step 1:
7 divided by 821 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 821

On to step 2:
821 can be fit into 79 0 times, resulting in a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 821

Moving on to step 3:
If we divide 794 by 821, we get 0 and a remainder of 794.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 794 and we're left with 794.
Fetch the next digit (5) from the dividend, attach it to 794 and continue: 7945 / 821

Going ahead to step 4:
821 can be fit into 7945 9 times, resulting in a remainder of 556.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7389 from 7945, we get 556.
Take the next digit (0) from the dividend and append it to 556, then repeat: 5560 / 821

Advancing to step 5:
821 can be fit into 5560 6 times, resulting in a remainder of 634.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 4926 from 5560 to get 634.
Append the next digit (9) from the dividend to 634 and continue with: 6349 / 821

On to step 6:
When dividing 6349 by 821, we get 7 with a remainder of 602.
Use 7 as the next digit of our solution. 
Result so far: 967.0
If we take 5747 away from 6349, we end up with 602.
Bring next digit (9) of the dividend behind the 602 and repeat the process: 6029 / 821

Advancing to step 7:
6029 divided by 821 is 7 with a remainder of 282.
The number 7 becomes the next digit in our result. 
Result so far: 9677.0
Subtracting 5747 from 6029 leaves us with 282.
Take the next digit (0) from the dividend and append it to 282, then repeat: 2820 / 821

Moving on to step 8:
If we divide 2820 by 821, we get 3 and a remainder of 357.
Record the quotient 3 as the next digit in the result. 
Result so far: 96773.0
If we subtract 2463 from 2820, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 9:
821 can be fit into 3570 4 times, resulting in a remainder of 286.
The next digit of our result is 4. 
Result so far: 96773.4
If we subtract 3284 from 3570, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
2860 divided by 821 is 3 with a remainder of 397.
The number 3 becomes the next digit in our result. 
Result so far: 96773.43
Subtract 2463 from 2860 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 11:
If we divide 3970 by 821, we get 4 and a remainder of 686.
Use 4 as the next digit of our solution. 
Result so far: 96773.434
Deduct 3284 from 3970 and we're left with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Let's proceed to step 12:
821 goes into 6860 8 times with a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 96773.4348
Subtract 6568 from 6860 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 13:
When dividing 2920 by 821, we get 3 with a remainder of 457.
The next digit of our result is 3. 
Result so far: 96773.43483
Deduct 2463 from 2920 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 14:
821 goes into 4570 5 times with a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 96773.434835
The remainder is 465 after subtracting 4105 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 15:
4650 divided by 821 is 5 with a remainder of 545.
The next digit of our result is 5. 
Result so far: 96773.4348355
The remainder is 545 after subtracting 4105 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

In conclusion, the division gives 96773.4348355 with a balance of 5.45e-06.
