Let's divide 20358535 by 391
Our goal is to divide 20358535 by 391.

On to step 1:
391 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 391

Advancing to step 2:
When dividing 20 by 391, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 391

Let's proceed to step 3:
If we divide 203 by 391, we get 0 and a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Bring next digit (5) of the dividend behind the 203 and repeat the process: 2035 / 391

Going ahead to step 4:
391 can be fit into 2035 5 times, resulting in a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 1955 from 2035 and we're left with 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 391

Going ahead to step 5:
If we divide 808 by 391, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtract 782 from 808 to get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 391

Going ahead to step 6:
When dividing 265 by 391, we get 0 with a remainder of 265.
The next digit of our result is 0. 
Result so far: 520.0
If we subtract 0 from 265, we get 265.
Grab the next digit (3) from the dividend, add it to 265, then carry on: 2653 / 391

Step 7:
If we divide 2653 by 391, we get 6 and a remainder of 307.
Record the quotient 6 as the next digit in the result. 
Result so far: 5206.0
If we take 2346 away from 2653, we end up with 307.
Append the next digit (5) from the dividend to 307 and continue with: 3075 / 391

Let's proceed to step 8:
When dividing 3075 by 391, we get 7 with a remainder of 338.
Record the quotient 7 as the next digit in the result. 
Result so far: 52067.0
The remainder is 338 after subtracting 2737 from 3075.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
The number 391 fits into 3380 8 times, leaving a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 52067.8
The remainder is 252 after subtracting 3128 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 10:
2520 divided by 391 is 6 with a remainder of 174.
The next digit of our result is 6. 
Result so far: 52067.86
Deduct 2346 from 2520 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 11:
When dividing 1740 by 391, we get 4 with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 52067.864
Subtracting 1564 from 1740 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 12:
391 goes into 1760 4 times with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 52067.8644
If we subtract 1564 from 1760, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 52067.8644, with a leftover of 0.00196.
