We look at the division of 49963563 by 359 
The aim is to understand the frequency of 359 in 49963563.

Step 1:
The number 359 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 359

Going ahead to step 2:
If we divide 49 by 359, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 359

Moving on to step 3:
The number 359 fits into 499 1 times, leaving a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 140 after subtracting 359 from 499.
Bring next digit (6) of the dividend behind the 140 and repeat the process: 1406 / 359

Advancing to step 4:
359 goes into 1406 3 times with a remainder of 329.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1077 from 1406 leaves us with 329.
Grab the next digit (3) from the dividend, add it to 329, then carry on: 3293 / 359

Advancing to step 5:
When dividing 3293 by 359, we get 9 with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 62 after subtracting 3231 from 3293.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 359

Let's proceed to step 6:
The number 359 fits into 625 1 times, leaving a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 1391.0
Subtracting 359 from 625 leaves us with 266.
Bring next digit (6) of the dividend behind the 266 and repeat the process: 2666 / 359

Moving on to step 7:
The number 359 fits into 2666 7 times, leaving a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 13917.0
If we subtract 2513 from 2666, we get 153.
Fetch the next digit (3) from the dividend, attach it to 153 and continue: 1533 / 359

Going ahead to step 8:
359 goes into 1533 4 times with a remainder of 97.
The next digit of our result is 4. 
Result so far: 139174.0
Subtract 1436 from 1533 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
359 goes into 970 2 times with a remainder of 252.
The next digit of our result is 2. 
Result so far: 139174.2
Subtracting 718 from 970 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 10:
When dividing 2520 by 359, we get 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 139174.27
Subtracting 2513 from 2520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
If we divide 70 by 359, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 139174.27
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
If we divide 700 by 359, we get 1 and a remainder of 341.
The next digit of our result is 1. 
Result so far: 139174.2701
If we subtract 359 from 700, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 13:
When dividing 3410 by 359, we get 9 with a remainder of 179.
Write down 9 as next digit of the result. 
Result so far: 139174.27019
Deduct 3231 from 3410 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 14:
The number 359 fits into 1790 4 times, leaving a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 139174.270194
Deduct 1436 from 1790 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 15:
3540 divided by 359 is 9 with a remainder of 309.
The number 9 becomes the next digit in our result. 
Result so far: 139174.2701949
If we take 3231 away from 3540, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 16:
The number 359 fits into 3090 8 times, leaving a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 139174.27019498
If we take 2872 away from 3090, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 139174.27019498, with a leftover of 2.18e-07.
