We look at the division of 13778520 by 437 
We want to figure out the number of times 13778520 can be divided by 437.

Let's proceed to step 1:
When dividing 1 by 437, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 437

Advancing to step 2:
13 divided by 437 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 437

Going ahead to step 3:
The number 437 fits into 137 0 times, leaving a remainder of 137.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 137, we get 137.
Include the next digit (7) from the dividend after 137, then repeat: 1377 / 437

Advancing to step 4:
The number 437 fits into 1377 3 times, leaving a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1311 away from 1377, we end up with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 437

Advancing to step 5:
668 divided by 437 is 1 with a remainder of 231.
The next digit of our result is 1. 
Result so far: 31.0
If we take 437 away from 668, we end up with 231.
Take the next digit (5) from the dividend and append it to 231, then repeat: 2315 / 437

Moving on to step 6:
When dividing 2315 by 437, we get 5 with a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 315.0
If we subtract 2185 from 2315, we get 130.
Take the next digit (2) from the dividend and append it to 130, then repeat: 1302 / 437

On to step 7:
The number 437 fits into 1302 2 times, leaving a remainder of 428.
The next digit of our result is 2. 
Result so far: 3152.0
Subtracting 874 from 1302 leaves us with 428.
Bring next digit (0) of the dividend behind the 428 and repeat the process: 4280 / 437

Step 8:
4280 divided by 437 is 9 with a remainder of 347.
The next digit of our result is 9. 
Result so far: 31529.0
If we take 3933 away from 4280, we end up with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 9:
When dividing 3470 by 437, we get 7 with a remainder of 411.
The next digit of our result is 7. 
Result so far: 31529.7
The remainder is 411 after subtracting 3059 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Step 10:
If we divide 4110 by 437, we get 9 and a remainder of 177.
Write down 9 as next digit of the result. 
Result so far: 31529.79
Subtract 3933 from 4110 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

On to step 11:
437 goes into 1770 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 31529.794
Deduct 1748 from 1770 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
The number 437 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 31529.794
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
437 can be fit into 2200 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 31529.79405
Subtract 2185 from 2200 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
150 divided by 437 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 31529.79405
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
When dividing 1500 by 437, we get 3 with a remainder of 189.
The next digit of our result is 3. 
Result so far: 31529.7940503
If we subtract 1311 from 1500, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 16:
If we divide 1890 by 437, we get 4 and a remainder of 142.
The next digit of our result is 4. 
Result so far: 31529.79405034
Deduct 1748 from 1890 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final outcome is 31529.79405034, with a leftover of 1.42e-07.
