We divide 354521 by 81
We want to divide 354521 by 81.

Moving on to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 81

Step 2:
81 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 81

Let's proceed to step 3:
The number 81 fits into 354 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 324 from 354, we get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 81

Step 4:
81 can be fit into 305 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 243 away from 305, we end up with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 81

Advancing to step 5:
If we divide 622 by 81, we get 7 and a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 437.0
If we subtract 567 from 622, we get 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 81

Advancing to step 6:
When dividing 551 by 81, we get 6 with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 4376.0
Subtract 486 from 551 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
If we divide 650 by 81, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 4376.8
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 81, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4376.8
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 4376.802
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
81 goes into 380 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4376.8024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
560 divided by 81 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 4376.80246
Subtracting 486 from 560 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
740 divided by 81 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4376.802469
If we take 729 away from 740, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
When dividing 110 by 81, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 4376.8024691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
When dividing 290 by 81, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 4376.80246913
Subtract 243 from 290 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 4376.80246913, and the remainder is 4.7e-08.
