We divide 87130123 by 434
The aim is to understand the frequency of 434 in 87130123.

Step 1:
When dividing 8 by 434, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 434

Advancing to step 2:
87 divided by 434 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (1) from the dividend, add it to 87, then carry on: 871 / 434

Let's proceed to step 3:
434 can be fit into 871 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 868 from 871, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 434

Going ahead to step 4:
If we divide 33 by 434, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 33, we end up with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 434

On to step 5:
434 can be fit into 330 0 times, resulting in a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 200.0
Deduct 0 from 330 and we're left with 330.
Fetch the next digit (1) from the dividend, attach it to 330 and continue: 3301 / 434

Advancing to step 6:
If we divide 3301 by 434, we get 7 and a remainder of 263.
Put 7 as the next digit of the answer. 
Result so far: 2007.0
Subtracting 3038 from 3301 leaves us with 263.
Bring next digit (2) of the dividend behind the 263 and repeat the process: 2632 / 434

Going ahead to step 7:
434 goes into 2632 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 20076.0
If we subtract 2604 from 2632, we get 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 434

Step 8:
If we divide 283 by 434, we get 0 and a remainder of 283.
Put 0 as the next digit of the answer. 
Result so far: 200760.0
Deduct 0 from 283 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 9:
434 goes into 2830 6 times with a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 200760.6
If we take 2604 away from 2830, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
2260 divided by 434 is 5 with a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 200760.65
Deduct 2170 from 2260 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
When dividing 900 by 434, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 200760.652
If we subtract 868 from 900, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
The number 434 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 200760.652
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
3200 divided by 434 is 7 with a remainder of 162.
Write down 7 as next digit of the result. 
Result so far: 200760.65207
If we subtract 3038 from 3200, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 14:
If we divide 1620 by 434, we get 3 and a remainder of 318.
Use 3 as the next digit of our solution. 
Result so far: 200760.652073
Deduct 1302 from 1620 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 15:
3180 divided by 434 is 7 with a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 200760.6520737
If we subtract 3038 from 3180, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 16:
When dividing 1420 by 434, we get 3 with a remainder of 118.
The number 3 becomes the next digit in our result. 
Result so far: 200760.65207373
Subtract 1302 from 1420 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final outcome is 200760.65207373, with a leftover of 1.18e-07.
