Let's divide 13155971 by 437
We want to figure out the number of times 13155971 can be divided by 437.

Moving on to step 1:
When dividing 1 by 437, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 437

Moving on to step 2:
If we divide 13 by 437, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 437

Advancing to step 3:
437 goes into 131 0 times with a remainder of 131.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 131 and we're left with 131.
Bring next digit (5) of the dividend behind the 131 and repeat the process: 1315 / 437

Advancing to step 4:
When dividing 1315 by 437, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1311 from 1315 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 437

Advancing to step 5:
The number 437 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 45 to get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 437

Moving on to step 6:
459 divided by 437 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 301.0
Subtracting 437 from 459 leaves us with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 437

Let's proceed to step 7:
The number 437 fits into 227 0 times, leaving a remainder of 227.
Write down 0 as next digit of the result. 
Result so far: 3010.0
If we take 0 away from 227, we end up with 227.
Grab the next digit (1) from the dividend, add it to 227, then carry on: 2271 / 437

Step 8:
If we divide 2271 by 437, we get 5 and a remainder of 86.
The next digit of our result is 5. 
Result so far: 30105.0
The remainder is 86 after subtracting 2185 from 2271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 9:
If we divide 860 by 437, we get 1 and a remainder of 423.
Record the quotient 1 as the next digit in the result. 
Result so far: 30105.1
If we subtract 437 from 860, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 10:
The number 437 fits into 4230 9 times, leaving a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 30105.19
The remainder is 297 after subtracting 3933 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 11:
If we divide 2970 by 437, we get 6 and a remainder of 348.
The number 6 becomes the next digit in our result. 
Result so far: 30105.196
Subtract 2622 from 2970 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 12:
437 can be fit into 3480 7 times, resulting in a remainder of 421.
Put 7 as the next digit of the answer. 
Result so far: 30105.1967
Subtracting 3059 from 3480 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 13:
437 can be fit into 4210 9 times, resulting in a remainder of 277.
The next digit of our result is 9. 
Result so far: 30105.19679
If we take 3933 away from 4210, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Going ahead to step 14:
If we divide 2770 by 437, we get 6 and a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 30105.196796
The remainder is 148 after subtracting 2622 from 2770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
The number 437 fits into 1480 3 times, leaving a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 30105.1967963
Subtracting 1311 from 1480 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 16:
437 goes into 1690 3 times with a remainder of 379.
Put 3 as the next digit of the answer. 
Result so far: 30105.19679633
Subtract 1311 from 1690 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

In conclusion, the division gives 30105.19679633 with a balance of 3.79e-07.
