We divide 91425302 by 821
We want to figure out the number of times 91425302 can be divided by 821.

Step 1:
The number 821 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 821

Moving on to step 2:
If we divide 91 by 821, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Include the next digit (4) from the dividend after 91, then repeat: 914 / 821

Moving on to step 3:
914 divided by 821 is 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 821 from 914 and we're left with 93.
Append the next digit (2) from the dividend to 93 and continue with: 932 / 821

Going ahead to step 4:
When dividing 932 by 821, we get 1 with a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 821 from 932, we get 111.
Take the next digit (5) from the dividend and append it to 111, then repeat: 1115 / 821

Let's proceed to step 5:
The number 821 fits into 1115 1 times, leaving a remainder of 294.
Put 1 as the next digit of the answer. 
Result so far: 111.0
Subtracting 821 from 1115 leaves us with 294.
Append the next digit (3) from the dividend to 294 and continue with: 2943 / 821

On to step 6:
821 can be fit into 2943 3 times, resulting in a remainder of 480.
The number 3 becomes the next digit in our result. 
Result so far: 1113.0
If we take 2463 away from 2943, we end up with 480.
Take the next digit (0) from the dividend and append it to 480, then repeat: 4800 / 821

On to step 7:
821 can be fit into 4800 5 times, resulting in a remainder of 695.
Use 5 as the next digit of our solution. 
Result so far: 11135.0
Deduct 4105 from 4800 and we're left with 695.
Bring next digit (2) of the dividend behind the 695 and repeat the process: 6952 / 821

Moving on to step 8:
6952 divided by 821 is 8 with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 111358.0
Deduct 6568 from 6952 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 9:
821 goes into 3840 4 times with a remainder of 556.
Put 4 as the next digit of the answer. 
Result so far: 111358.4
If we subtract 3284 from 3840, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 10:
821 goes into 5560 6 times with a remainder of 634.
The next digit of our result is 6. 
Result so far: 111358.46
Subtracting 4926 from 5560 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

On to step 11:
821 can be fit into 6340 7 times, resulting in a remainder of 593.
Put 7 as the next digit of the answer. 
Result so far: 111358.467
Deduct 5747 from 6340 and we're left with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Going ahead to step 12:
If we divide 5930 by 821, we get 7 and a remainder of 183.
The number 7 becomes the next digit in our result. 
Result so far: 111358.4677
Deduct 5747 from 5930 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final outcome is 111358.4677, with a leftover of 0.00183.
