48700579 divided by 351 
The aim is to understand the frequency of 351 in 48700579.

Moving on to step 1:
When dividing 4 by 351, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 351

On to step 2:
When dividing 48 by 351, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 351

Step 3:
The number 351 fits into 487 1 times, leaving a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 351 from 487, we get 136.
Fetch the next digit (0) from the dividend, attach it to 136 and continue: 1360 / 351

On to step 4:
351 can be fit into 1360 3 times, resulting in a remainder of 307.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1053 from 1360 leaves us with 307.
Fetch the next digit (0) from the dividend, attach it to 307 and continue: 3070 / 351

On to step 5:
351 goes into 3070 8 times with a remainder of 262.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Deduct 2808 from 3070 and we're left with 262.
Fetch the next digit (5) from the dividend, attach it to 262 and continue: 2625 / 351

Going ahead to step 6:
2625 divided by 351 is 7 with a remainder of 168.
Use 7 as the next digit of our solution. 
Result so far: 1387.0
Subtracting 2457 from 2625 leaves us with 168.
Fetch the next digit (7) from the dividend, attach it to 168 and continue: 1687 / 351

Let's proceed to step 7:
1687 divided by 351 is 4 with a remainder of 283.
Write down 4 as next digit of the result. 
Result so far: 13874.0
Subtract 1404 from 1687 to get 283.
Append the next digit (9) from the dividend to 283 and continue with: 2839 / 351

Step 8:
If we divide 2839 by 351, we get 8 and a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 138748.0
Subtracting 2808 from 2839 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
The number 351 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 138748.0
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
351 goes into 3100 8 times with a remainder of 292.
The next digit of our result is 8. 
Result so far: 138748.08
Subtract 2808 from 3100 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 11:
351 goes into 2920 8 times with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 138748.088
The remainder is 112 after subtracting 2808 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 138748.088, with a leftover of 0.0112.
