We look at the division of 15878629 by 834 
The aim is to understand the frequency of 834 in 15878629.

Moving on to step 1:
If we divide 1 by 834, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 834

Going ahead to step 2:
If we divide 15 by 834, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 834

Let's proceed to step 3:
834 can be fit into 158 0 times, resulting in a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Grab the next digit (7) from the dividend, add it to 158, then carry on: 1587 / 834

Moving on to step 4:
When dividing 1587 by 834, we get 1 with a remainder of 753.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 834 from 1587 to get 753.
Grab the next digit (8) from the dividend, add it to 753, then carry on: 7538 / 834

Step 5:
834 can be fit into 7538 9 times, resulting in a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 7506 from 7538 leaves us with 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 834

On to step 6:
If we divide 326 by 834, we get 0 and a remainder of 326.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
The remainder is 326 after subtracting 0 from 326.
Take the next digit (2) from the dividend and append it to 326, then repeat: 3262 / 834

On to step 7:
The number 834 fits into 3262 3 times, leaving a remainder of 760.
Put 3 as the next digit of the answer. 
Result so far: 1903.0
If we subtract 2502 from 3262, we get 760.
Bring next digit (9) of the dividend behind the 760 and repeat the process: 7609 / 834

Let's proceed to step 8:
834 goes into 7609 9 times with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 19039.0
The remainder is 103 after subtracting 7506 from 7609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 9:
The number 834 fits into 1030 1 times, leaving a remainder of 196.
The next digit of our result is 1. 
Result so far: 19039.1
The remainder is 196 after subtracting 834 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 10:
If we divide 1960 by 834, we get 2 and a remainder of 292.
Use 2 as the next digit of our solution. 
Result so far: 19039.12
The remainder is 292 after subtracting 1668 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 11:
If we divide 2920 by 834, we get 3 and a remainder of 418.
The number 3 becomes the next digit in our result. 
Result so far: 19039.123
Subtracting 2502 from 2920 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 12:
834 goes into 4180 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 19039.1235
If we subtract 4170 from 4180, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 834, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 19039.1235
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
834 can be fit into 1000 1 times, resulting in a remainder of 166.
The next digit of our result is 1. 
Result so far: 19039.123501
If we take 834 away from 1000, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 15:
1660 divided by 834 is 1 with a remainder of 826.
Put 1 as the next digit of the answer. 
Result so far: 19039.1235011
If we take 834 away from 1660, we end up with 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

The final outcome is 19039.1235011, with a leftover of 8.26e-06.
