We look at the division of 3547581 by 391 
We want to divide 3547581 by 391.

Moving on to step 1:
When dividing 3 by 391, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 391

Moving on to step 2:
391 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 391

Let's proceed to step 3:
391 goes into 354 0 times with a remainder of 354.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 354 and we're left with 354.
Append the next digit (7) from the dividend to 354 and continue with: 3547 / 391

Let's proceed to step 4:
When dividing 3547 by 391, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 3519 from 3547 and we're left with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 391

Advancing to step 5:
285 divided by 391 is 0 with a remainder of 285.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Deduct 0 from 285 and we're left with 285.
Fetch the next digit (8) from the dividend, attach it to 285 and continue: 2858 / 391

Step 6:
If we divide 2858 by 391, we get 7 and a remainder of 121.
Put 7 as the next digit of the answer. 
Result so far: 907.0
Subtracting 2737 from 2858 leaves us with 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 391

On to step 7:
The number 391 fits into 1211 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 9073.0
Subtract 1173 from 1211 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
391 can be fit into 380 0 times, resulting in a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 9073.0
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 9:
If we divide 3800 by 391, we get 9 and a remainder of 281.
The next digit of our result is 9. 
Result so far: 9073.09
The remainder is 281 after subtracting 3519 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 10:
391 goes into 2810 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 9073.097
Subtract 2737 from 2810 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
391 goes into 730 1 times with a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 9073.0971
If we take 391 away from 730, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 12:
391 goes into 3390 8 times with a remainder of 262.
Put 8 as the next digit of the answer. 
Result so far: 9073.09718
If we take 3128 away from 3390, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 13:
391 goes into 2620 6 times with a remainder of 274.
Record the quotient 6 as the next digit in the result. 
Result so far: 9073.097186
Deduct 2346 from 2620 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 14:
391 can be fit into 2740 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9073.0971867
Subtract 2737 from 2740 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 15:
When dividing 30 by 391, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 9073.0971867
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 9073.0971867 and a remainder of 3e-08.
