We divide 58395139 by 399
The aim is to understand the frequency of 399 in 58395139.

Step 1:
5 divided by 399 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 399

Moving on to step 2:
The number 399 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 399

On to step 3:
583 divided by 399 is 1 with a remainder of 184.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 399 from 583 to get 184.
Append the next digit (9) from the dividend to 184 and continue with: 1849 / 399

Advancing to step 4:
When dividing 1849 by 399, we get 4 with a remainder of 253.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1596 from 1849 leaves us with 253.
Bring next digit (5) of the dividend behind the 253 and repeat the process: 2535 / 399

Going ahead to step 5:
399 can be fit into 2535 6 times, resulting in a remainder of 141.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtracting 2394 from 2535 leaves us with 141.
Include the next digit (1) from the dividend after 141, then repeat: 1411 / 399

Step 6:
When dividing 1411 by 399, we get 3 with a remainder of 214.
Use 3 as the next digit of our solution. 
Result so far: 1463.0
The remainder is 214 after subtracting 1197 from 1411.
Fetch the next digit (3) from the dividend, attach it to 214 and continue: 2143 / 399

Moving on to step 7:
The number 399 fits into 2143 5 times, leaving a remainder of 148.
Use 5 as the next digit of our solution. 
Result so far: 14635.0
Deduct 1995 from 2143 and we're left with 148.
Grab the next digit (9) from the dividend, add it to 148, then carry on: 1489 / 399

Moving on to step 8:
399 goes into 1489 3 times with a remainder of 292.
The number 3 becomes the next digit in our result. 
Result so far: 146353.0
Subtracting 1197 from 1489 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 9:
The number 399 fits into 2920 7 times, leaving a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 146353.7
Subtract 2793 from 2920 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 10:
If we divide 1270 by 399, we get 3 and a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 146353.73
Subtracting 1197 from 1270 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 11:
399 goes into 730 1 times with a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 146353.731
If we subtract 399 from 730, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 12:
399 can be fit into 3310 8 times, resulting in a remainder of 118.
Write down 8 as next digit of the result. 
Result so far: 146353.7318
Subtract 3192 from 3310 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.

Advancing to step 13:
399 can be fit into 1180 2 times, resulting in a remainder of 382.
Use 2 as the next digit of our solution. 
Result so far: 146353.73182
Subtract 798 from 1180 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 14:
399 goes into 3820 9 times with a remainder of 229.
Use 9 as the next digit of our solution. 
Result so far: 146353.731829
Subtracting 3591 from 3820 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 15:
399 goes into 2290 5 times with a remainder of 295.
The next digit of our result is 5. 
Result so far: 146353.7318295
Subtract 1995 from 2290 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 16:
When dividing 2950 by 399, we get 7 with a remainder of 157.
The next digit of our result is 7. 
Result so far: 146353.73182957
Subtract 2793 from 2950 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

The quotient of the division is 146353.73182957, and the remainder is 1.57e-07.
