We look at the division of 90568543 by 391 
Our goal is to divide 90568543 by 391.

Step 1:
The number 391 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 391

On to step 2:
The number 391 fits into 90 0 times, leaving a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 391

On to step 3:
905 divided by 391 is 2 with a remainder of 123.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 782 from 905 leaves us with 123.
Take the next digit (6) from the dividend and append it to 123, then repeat: 1236 / 391

Step 4:
391 goes into 1236 3 times with a remainder of 63.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 1173 from 1236, we get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 391

Let's proceed to step 5:
391 goes into 638 1 times with a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 231.0
If we take 391 away from 638, we end up with 247.
Include the next digit (5) from the dividend after 247, then repeat: 2475 / 391

On to step 6:
391 goes into 2475 6 times with a remainder of 129.
The number 6 becomes the next digit in our result. 
Result so far: 2316.0
Deduct 2346 from 2475 and we're left with 129.
Fetch the next digit (4) from the dividend, attach it to 129 and continue: 1294 / 391

Going ahead to step 7:
When dividing 1294 by 391, we get 3 with a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 23163.0
Subtract 1173 from 1294 to get 121.
Grab the next digit (3) from the dividend, add it to 121, then carry on: 1213 / 391

Advancing to step 8:
391 can be fit into 1213 3 times, resulting in a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 231633.0
If we subtract 1173 from 1213, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
391 goes into 400 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 231633.1
If we subtract 391 from 400, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
391 can be fit into 90 0 times, resulting in a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 231633.1
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
When dividing 900 by 391, we get 2 with a remainder of 118.
Record the quotient 2 as the next digit in the result. 
Result so far: 231633.102
Deduct 782 from 900 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 12:
The number 391 fits into 1180 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 231633.1023
Deduct 1173 from 1180 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
391 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 231633.1023
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
391 can be fit into 700 1 times, resulting in a remainder of 309.
The next digit of our result is 1. 
Result so far: 231633.102301
Subtracting 391 from 700 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 15:
When dividing 3090 by 391, we get 7 with a remainder of 353.
The number 7 becomes the next digit in our result. 
Result so far: 231633.1023017
Subtract 2737 from 3090 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 16:
When dividing 3530 by 391, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 231633.10230179
Subtract 3519 from 3530 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 231633.10230179 with a balance of 1.1e-08.
