We divide 3996051 by 821
We're looking to find how many times 821 goes into 3996051.

Step 1:
If we divide 3 by 821, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 821

On to step 2:
When dividing 39 by 821, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 821

On to step 3:
821 goes into 399 0 times with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Take the next digit (6) from the dividend and append it to 399, then repeat: 3996 / 821

Let's proceed to step 4:
821 can be fit into 3996 4 times, resulting in a remainder of 712.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3284 away from 3996, we end up with 712.
Fetch the next digit (0) from the dividend, attach it to 712 and continue: 7120 / 821

Advancing to step 5:
The number 821 fits into 7120 8 times, leaving a remainder of 552.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 6568 from 7120 to get 552.
Fetch the next digit (5) from the dividend, attach it to 552 and continue: 5525 / 821

Step 6:
5525 divided by 821 is 6 with a remainder of 599.
Record the quotient 6 as the next digit in the result. 
Result so far: 486.0
If we take 4926 away from 5525, we end up with 599.
Take the next digit (1) from the dividend and append it to 599, then repeat: 5991 / 821

Let's proceed to step 7:
5991 divided by 821 is 7 with a remainder of 244.
Write down 7 as next digit of the result. 
Result so far: 4867.0
If we subtract 5747 from 5991, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 8:
821 goes into 2440 2 times with a remainder of 798.
The next digit of our result is 2. 
Result so far: 4867.2
Subtracting 1642 from 2440 leaves us with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Moving on to step 9:
When dividing 7980 by 821, we get 9 with a remainder of 591.
Put 9 as the next digit of the answer. 
Result so far: 4867.29
If we subtract 7389 from 7980, we get 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Let's proceed to step 10:
The number 821 fits into 5910 7 times, leaving a remainder of 163.
Use 7 as the next digit of our solution. 
Result so far: 4867.297
If we subtract 5747 from 5910, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 11:
821 can be fit into 1630 1 times, resulting in a remainder of 809.
The number 1 becomes the next digit in our result. 
Result so far: 4867.2971
The remainder is 809 after subtracting 821 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Advancing to step 12:
When dividing 8090 by 821, we get 9 with a remainder of 701.
Write down 9 as next digit of the result. 
Result so far: 4867.29719
Subtracting 7389 from 8090 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Going ahead to step 13:
When dividing 7010 by 821, we get 8 with a remainder of 442.
Use 8 as the next digit of our solution. 
Result so far: 4867.297198
Deduct 6568 from 7010 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 14:
821 can be fit into 4420 5 times, resulting in a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 4867.2971985
Deduct 4105 from 4420 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 15:
The number 821 fits into 3150 3 times, leaving a remainder of 687.
Write down 3 as next digit of the result. 
Result so far: 4867.29719853
The remainder is 687 after subtracting 2463 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Our division results in 4867.29719853 with a remaining 6.87e-07.
