We look at the division of 15803052 by 739 
The aim is to understand the frequency of 739 in 15803052.

Advancing to step 1:
1 divided by 739 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 739

Advancing to step 2:
The number 739 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 739

On to step 3:
When dividing 158 by 739, we get 0 with a remainder of 158.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Take the next digit (0) from the dividend and append it to 158, then repeat: 1580 / 739

Going ahead to step 4:
If we divide 1580 by 739, we get 2 and a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1478 from 1580, we get 102.
Bring next digit (3) of the dividend behind the 102 and repeat the process: 1023 / 739

Let's proceed to step 5:
If we divide 1023 by 739, we get 1 and a remainder of 284.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 739 from 1023, we get 284.
Fetch the next digit (0) from the dividend, attach it to 284 and continue: 2840 / 739

Going ahead to step 6:
2840 divided by 739 is 3 with a remainder of 623.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Deduct 2217 from 2840 and we're left with 623.
Include the next digit (5) from the dividend after 623, then repeat: 6235 / 739

On to step 7:
6235 divided by 739 is 8 with a remainder of 323.
Record the quotient 8 as the next digit in the result. 
Result so far: 2138.0
The remainder is 323 after subtracting 5912 from 6235.
Grab the next digit (2) from the dividend, add it to 323, then carry on: 3232 / 739

Moving on to step 8:
739 can be fit into 3232 4 times, resulting in a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 21384.0
Subtract 2956 from 3232 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 9:
When dividing 2760 by 739, we get 3 with a remainder of 543.
The number 3 becomes the next digit in our result. 
Result so far: 21384.3
Subtracting 2217 from 2760 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Going ahead to step 10:
739 can be fit into 5430 7 times, resulting in a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 21384.37
Subtracting 5173 from 5430 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 11:
The number 739 fits into 2570 3 times, leaving a remainder of 353.
Record the quotient 3 as the next digit in the result. 
Result so far: 21384.373
Deduct 2217 from 2570 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Step 12:
739 can be fit into 3530 4 times, resulting in a remainder of 574.
Use 4 as the next digit of our solution. 
Result so far: 21384.3734
Subtracting 2956 from 3530 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 13:
When dividing 5740 by 739, we get 7 with a remainder of 567.
Put 7 as the next digit of the answer. 
Result so far: 21384.37347
If we subtract 5173 from 5740, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

On to step 14:
739 goes into 5670 7 times with a remainder of 497.
Put 7 as the next digit of the answer. 
Result so far: 21384.373477
Deduct 5173 from 5670 and we're left with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

After the division, we end up with 21384.373477 and a remainder of 4.97e-05.
