We look at the division of 20051139 by 437 
Let's see how many times 437 fits into 20051139.

On to step 1:
When dividing 2 by 437, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 437

Moving on to step 2:
The number 437 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 437

Moving on to step 3:
When dividing 200 by 437, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 200 and we're left with 200.
Include the next digit (5) from the dividend after 200, then repeat: 2005 / 437

Step 4:
When dividing 2005 by 437, we get 4 with a remainder of 257.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1748 from 2005 leaves us with 257.
Bring next digit (1) of the dividend behind the 257 and repeat the process: 2571 / 437

Going ahead to step 5:
437 goes into 2571 5 times with a remainder of 386.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 2185 from 2571, we get 386.
Grab the next digit (1) from the dividend, add it to 386, then carry on: 3861 / 437

Advancing to step 6:
437 can be fit into 3861 8 times, resulting in a remainder of 365.
Write down 8 as next digit of the result. 
Result so far: 458.0
If we subtract 3496 from 3861, we get 365.
Take the next digit (3) from the dividend and append it to 365, then repeat: 3653 / 437

On to step 7:
The number 437 fits into 3653 8 times, leaving a remainder of 157.
The number 8 becomes the next digit in our result. 
Result so far: 4588.0
Deduct 3496 from 3653 and we're left with 157.
Take the next digit (9) from the dividend and append it to 157, then repeat: 1579 / 437

Moving on to step 8:
When dividing 1579 by 437, we get 3 with a remainder of 268.
Write down 3 as next digit of the result. 
Result so far: 45883.0
If we subtract 1311 from 1579, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 9:
437 can be fit into 2680 6 times, resulting in a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 45883.6
Deduct 2622 from 2680 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
437 can be fit into 580 1 times, resulting in a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 45883.61
Subtracting 437 from 580 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 11:
437 can be fit into 1430 3 times, resulting in a remainder of 119.
The next digit of our result is 3. 
Result so far: 45883.613
The remainder is 119 after subtracting 1311 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 12:
1190 divided by 437 is 2 with a remainder of 316.
The number 2 becomes the next digit in our result. 
Result so far: 45883.6132
Subtracting 874 from 1190 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 13:
437 can be fit into 3160 7 times, resulting in a remainder of 101.
Put 7 as the next digit of the answer. 
Result so far: 45883.61327
Subtract 3059 from 3160 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 14:
When dividing 1010 by 437, we get 2 with a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 45883.613272
Deduct 874 from 1010 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
1360 divided by 437 is 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 45883.6132723
The remainder is 49 after subtracting 1311 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
If we divide 490 by 437, we get 1 and a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 45883.61327231
If we take 437 away from 490, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final result is 45883.61327231 with a remainder of 5.3e-08.
