77150972 divided by 821 
We want to figure out the number of times 77150972 can be divided by 821.

Going ahead to step 1:
821 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 821

Step 2:
821 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 821

Advancing to step 3:
The number 821 fits into 771 0 times, leaving a remainder of 771.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 771 to get 771.
Fetch the next digit (5) from the dividend, attach it to 771 and continue: 7715 / 821

On to step 4:
When dividing 7715 by 821, we get 9 with a remainder of 326.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 326 after subtracting 7389 from 7715.
Fetch the next digit (0) from the dividend, attach it to 326 and continue: 3260 / 821

Advancing to step 5:
If we divide 3260 by 821, we get 3 and a remainder of 797.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 2463 away from 3260, we end up with 797.
Fetch the next digit (9) from the dividend, attach it to 797 and continue: 7979 / 821

Moving on to step 6:
7979 divided by 821 is 9 with a remainder of 590.
The number 9 becomes the next digit in our result. 
Result so far: 939.0
Deduct 7389 from 7979 and we're left with 590.
Append the next digit (7) from the dividend to 590 and continue with: 5907 / 821

Step 7:
5907 divided by 821 is 7 with a remainder of 160.
The next digit of our result is 7. 
Result so far: 9397.0
Deduct 5747 from 5907 and we're left with 160.
Bring next digit (2) of the dividend behind the 160 and repeat the process: 1602 / 821

Step 8:
821 goes into 1602 1 times with a remainder of 781.
Record the quotient 1 as the next digit in the result. 
Result so far: 93971.0
Subtracting 821 from 1602 leaves us with 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Step 9:
The number 821 fits into 7810 9 times, leaving a remainder of 421.
Write down 9 as next digit of the result. 
Result so far: 93971.9
Deduct 7389 from 7810 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 10:
4210 divided by 821 is 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 93971.95
The remainder is 105 after subtracting 4105 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 11:
821 can be fit into 1050 1 times, resulting in a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 93971.951
Subtract 821 from 1050 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 12:
If we divide 2290 by 821, we get 2 and a remainder of 648.
Write down 2 as next digit of the result. 
Result so far: 93971.9512
Deduct 1642 from 2290 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 13:
When dividing 6480 by 821, we get 7 with a remainder of 733.
The next digit of our result is 7. 
Result so far: 93971.95127
Deduct 5747 from 6480 and we're left with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Step 14:
821 can be fit into 7330 8 times, resulting in a remainder of 762.
The next digit of our result is 8. 
Result so far: 93971.951278
If we take 6568 away from 7330, we end up with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Step 15:
The number 821 fits into 7620 9 times, leaving a remainder of 231.
The next digit of our result is 9. 
Result so far: 93971.9512789
The remainder is 231 after subtracting 7389 from 7620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 16:
821 goes into 2310 2 times with a remainder of 668.
The next digit of our result is 2. 
Result so far: 93971.95127892
Subtracting 1642 from 2310 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

In conclusion, the division gives 93971.95127892 with a balance of 6.68e-07.
