56297398 divided by 354 
The aim is to understand the frequency of 354 in 56297398.

Going ahead to step 1:
When dividing 5 by 354, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 354

Advancing to step 2:
If we divide 56 by 354, we get 0 and a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 354

Step 3:
562 divided by 354 is 1 with a remainder of 208.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 354 from 562 to get 208.
Grab the next digit (9) from the dividend, add it to 208, then carry on: 2089 / 354

On to step 4:
2089 divided by 354 is 5 with a remainder of 319.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 1770 away from 2089, we end up with 319.
Grab the next digit (7) from the dividend, add it to 319, then carry on: 3197 / 354

Step 5:
When dividing 3197 by 354, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Subtract 3186 from 3197 to get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 354

Let's proceed to step 6:
If we divide 113 by 354, we get 0 and a remainder of 113.
Use 0 as the next digit of our solution. 
Result so far: 1590.0
If we subtract 0 from 113, we get 113.
Append the next digit (9) from the dividend to 113 and continue with: 1139 / 354

Going ahead to step 7:
The number 354 fits into 1139 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 15903.0
Deduct 1062 from 1139 and we're left with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 354

On to step 8:
354 goes into 778 2 times with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 159032.0
The remainder is 70 after subtracting 708 from 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
700 divided by 354 is 1 with a remainder of 346.
Record the quotient 1 as the next digit in the result. 
Result so far: 159032.1
Subtracting 354 from 700 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 10:
3460 divided by 354 is 9 with a remainder of 274.
The number 9 becomes the next digit in our result. 
Result so far: 159032.19
Deduct 3186 from 3460 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 11:
354 goes into 2740 7 times with a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 159032.197
If we take 2478 away from 2740, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 12:
354 goes into 2620 7 times with a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 159032.1977
If we subtract 2478 from 2620, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final outcome is 159032.1977, with a leftover of 0.00142.
