We look at the division of 81636925 by 213 
We're looking to find how many times 213 goes into 81636925.

On to step 1:
213 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 213

Moving on to step 2:
213 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 213

Advancing to step 3:
213 can be fit into 816 3 times, resulting in a remainder of 177.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 639 from 816 leaves us with 177.
Include the next digit (3) from the dividend after 177, then repeat: 1773 / 213

Let's proceed to step 4:
1773 divided by 213 is 8 with a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 1704 from 1773, we get 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 213

Advancing to step 5:
213 can be fit into 696 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 383.0
If we take 639 away from 696, we end up with 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 213

Advancing to step 6:
213 can be fit into 579 2 times, resulting in a remainder of 153.
Record the quotient 2 as the next digit in the result. 
Result so far: 3832.0
Subtract 426 from 579 to get 153.
Include the next digit (2) from the dividend after 153, then repeat: 1532 / 213

Going ahead to step 7:
If we divide 1532 by 213, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 38327.0
If we subtract 1491 from 1532, we get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 213

Step 8:
The number 213 fits into 415 1 times, leaving a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 383271.0
If we subtract 213 from 415, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
If we divide 2020 by 213, we get 9 and a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 383271.9
Deduct 1917 from 2020 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 10:
When dividing 1030 by 213, we get 4 with a remainder of 178.
Write down 4 as next digit of the result. 
Result so far: 383271.94
Subtract 852 from 1030 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 11:
213 can be fit into 1780 8 times, resulting in a remainder of 76.
The next digit of our result is 8. 
Result so far: 383271.948
Subtracting 1704 from 1780 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
213 can be fit into 760 3 times, resulting in a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 383271.9483
The remainder is 121 after subtracting 639 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 13:
213 goes into 1210 5 times with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 383271.94835
Subtracting 1065 from 1210 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 14:
The number 213 fits into 1450 6 times, leaving a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 383271.948356
The remainder is 172 after subtracting 1278 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 15:
The number 213 fits into 1720 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 383271.9483568
If we take 1704 away from 1720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
160 divided by 213 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 383271.9483568
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 383271.9483568 with a remaining 1.6e-07.
