We're dividing 10543732 by 821 
Our goal is to divide 10543732 by 821.

Going ahead to step 1:
821 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 821

On to step 2:
When dividing 10 by 821, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 821

Going ahead to step 3:
The number 821 fits into 105 0 times, leaving a remainder of 105.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 105 and we're left with 105.
Bring next digit (4) of the dividend behind the 105 and repeat the process: 1054 / 821

Let's proceed to step 4:
821 goes into 1054 1 times with a remainder of 233.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 821 from 1054 to get 233.
Bring next digit (3) of the dividend behind the 233 and repeat the process: 2333 / 821

Step 5:
If we divide 2333 by 821, we get 2 and a remainder of 691.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1642 from 2333 to get 691.
Take the next digit (7) from the dividend and append it to 691, then repeat: 6917 / 821

On to step 6:
When dividing 6917 by 821, we get 8 with a remainder of 349.
Write down 8 as next digit of the result. 
Result so far: 128.0
Deduct 6568 from 6917 and we're left with 349.
Bring next digit (3) of the dividend behind the 349 and repeat the process: 3493 / 821

Going ahead to step 7:
When dividing 3493 by 821, we get 4 with a remainder of 209.
The number 4 becomes the next digit in our result. 
Result so far: 1284.0
If we take 3284 away from 3493, we end up with 209.
Fetch the next digit (2) from the dividend, attach it to 209 and continue: 2092 / 821

Going ahead to step 8:
2092 divided by 821 is 2 with a remainder of 450.
Write down 2 as next digit of the result. 
Result so far: 12842.0
The remainder is 450 after subtracting 1642 from 2092.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 9:
821 goes into 4500 5 times with a remainder of 395.
Use 5 as the next digit of our solution. 
Result so far: 12842.5
If we subtract 4105 from 4500, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 10:
821 can be fit into 3950 4 times, resulting in a remainder of 666.
Write down 4 as next digit of the result. 
Result so far: 12842.54
Subtracting 3284 from 3950 leaves us with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Let's proceed to step 11:
The number 821 fits into 6660 8 times, leaving a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 12842.548
The remainder is 92 after subtracting 6568 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
821 can be fit into 920 1 times, resulting in a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 12842.5481
Deduct 821 from 920 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 13:
990 divided by 821 is 1 with a remainder of 169.
The next digit of our result is 1. 
Result so far: 12842.54811
The remainder is 169 after subtracting 821 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The final outcome is 12842.54811, with a leftover of 0.000169.
