Let's divide 31149592 by 821
We want to figure out the number of times 31149592 can be divided by 821.

On to step 1:
When dividing 3 by 821, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 821

Advancing to step 2:
821 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 821

Advancing to step 3:
If we divide 311 by 821, we get 0 and a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 311 after subtracting 0 from 311.
Grab the next digit (4) from the dividend, add it to 311, then carry on: 3114 / 821

Advancing to step 4:
When dividing 3114 by 821, we get 3 with a remainder of 651.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2463 away from 3114, we end up with 651.
Include the next digit (9) from the dividend after 651, then repeat: 6519 / 821

Advancing to step 5:
When dividing 6519 by 821, we get 7 with a remainder of 772.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 5747 from 6519 and we're left with 772.
Grab the next digit (5) from the dividend, add it to 772, then carry on: 7725 / 821

Step 6:
7725 divided by 821 is 9 with a remainder of 336.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
Deduct 7389 from 7725 and we're left with 336.
Bring next digit (9) of the dividend behind the 336 and repeat the process: 3369 / 821

Going ahead to step 7:
The number 821 fits into 3369 4 times, leaving a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 3794.0
If we subtract 3284 from 3369, we get 85.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 821

On to step 8:
852 divided by 821 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 37941.0
If we take 821 away from 852, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
The number 821 fits into 310 0 times, leaving a remainder of 310.
The next digit of our result is 0. 
Result so far: 37941.0
If we take 0 away from 310, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
3100 divided by 821 is 3 with a remainder of 637.
Put 3 as the next digit of the answer. 
Result so far: 37941.03
Subtract 2463 from 3100 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Advancing to step 11:
6370 divided by 821 is 7 with a remainder of 623.
The next digit of our result is 7. 
Result so far: 37941.037
If we subtract 5747 from 6370, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 12:
If we divide 6230 by 821, we get 7 and a remainder of 483.
The number 7 becomes the next digit in our result. 
Result so far: 37941.0377
Subtracting 5747 from 6230 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Our division results in 37941.0377 with a remaining 0.00483.
