We're dividing 20542059 by 391 
We want to figure out the number of times 20542059 can be divided by 391.

On to step 1:
If we divide 2 by 391, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 391

Advancing to step 2:
If we divide 20 by 391, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 391

Advancing to step 3:
The number 391 fits into 205 0 times, leaving a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Take the next digit (4) from the dividend and append it to 205, then repeat: 2054 / 391

Moving on to step 4:
391 goes into 2054 5 times with a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1955 away from 2054, we end up with 99.
Grab the next digit (2) from the dividend, add it to 99, then carry on: 992 / 391

Moving on to step 5:
The number 391 fits into 992 2 times, leaving a remainder of 210.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 782 from 992, we get 210.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 391

On to step 6:
2100 divided by 391 is 5 with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
Subtracting 1955 from 2100 leaves us with 145.
Fetch the next digit (5) from the dividend, attach it to 145 and continue: 1455 / 391

Let's proceed to step 7:
The number 391 fits into 1455 3 times, leaving a remainder of 282.
Write down 3 as next digit of the result. 
Result so far: 5253.0
If we take 1173 away from 1455, we end up with 282.
Bring next digit (9) of the dividend behind the 282 and repeat the process: 2829 / 391

Moving on to step 8:
If we divide 2829 by 391, we get 7 and a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 52537.0
The remainder is 92 after subtracting 2737 from 2829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 9:
391 goes into 920 2 times with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 52537.2
Deduct 782 from 920 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 10:
1380 divided by 391 is 3 with a remainder of 207.
Write down 3 as next digit of the result. 
Result so far: 52537.23
If we take 1173 away from 1380, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 11:
When dividing 2070 by 391, we get 5 with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 52537.235
The remainder is 115 after subtracting 1955 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 12:
When dividing 1150 by 391, we get 2 with a remainder of 368.
Write down 2 as next digit of the result. 
Result so far: 52537.2352
Deduct 782 from 1150 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 13:
3680 divided by 391 is 9 with a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 52537.23529
The remainder is 161 after subtracting 3519 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 14:
If we divide 1610 by 391, we get 4 and a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 52537.235294
If we take 1564 away from 1610, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 15:
The number 391 fits into 460 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 52537.2352941
Subtract 391 from 460 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 16:
391 goes into 690 1 times with a remainder of 299.
Use 1 as the next digit of our solution. 
Result so far: 52537.23529411
Subtracting 391 from 690 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

In conclusion, the division gives 52537.23529411 with a balance of 2.99e-07.
