57450898 divided by 654 
The aim is to understand the frequency of 654 in 57450898.

On to step 1:
The number 654 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 654

Going ahead to step 2:
When dividing 57 by 654, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 654

Advancing to step 3:
The number 654 fits into 574 0 times, leaving a remainder of 574.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 574 and we're left with 574.
Bring next digit (5) of the dividend behind the 574 and repeat the process: 5745 / 654

On to step 4:
654 can be fit into 5745 8 times, resulting in a remainder of 513.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 5232 from 5745 leaves us with 513.
Append the next digit (0) from the dividend to 513 and continue with: 5130 / 654

Moving on to step 5:
5130 divided by 654 is 7 with a remainder of 552.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 4578 away from 5130, we end up with 552.
Fetch the next digit (8) from the dividend, attach it to 552 and continue: 5528 / 654

Advancing to step 6:
654 goes into 5528 8 times with a remainder of 296.
Use 8 as the next digit of our solution. 
Result so far: 878.0
If we take 5232 away from 5528, we end up with 296.
Take the next digit (9) from the dividend and append it to 296, then repeat: 2969 / 654

Step 7:
654 goes into 2969 4 times with a remainder of 353.
Write down 4 as next digit of the result. 
Result so far: 8784.0
Deduct 2616 from 2969 and we're left with 353.
Take the next digit (8) from the dividend and append it to 353, then repeat: 3538 / 654

Going ahead to step 8:
654 can be fit into 3538 5 times, resulting in a remainder of 268.
The next digit of our result is 5. 
Result so far: 87845.0
The remainder is 268 after subtracting 3270 from 3538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 9:
When dividing 2680 by 654, we get 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 87845.4
Deduct 2616 from 2680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
654 can be fit into 640 0 times, resulting in a remainder of 640.
The next digit of our result is 0. 
Result so far: 87845.4
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 11:
The number 654 fits into 6400 9 times, leaving a remainder of 514.
The next digit of our result is 9. 
Result so far: 87845.409
If we subtract 5886 from 6400, we get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 12:
5140 divided by 654 is 7 with a remainder of 562.
The next digit of our result is 7. 
Result so far: 87845.4097
If we take 4578 away from 5140, we end up with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Step 13:
If we divide 5620 by 654, we get 8 and a remainder of 388.
The next digit of our result is 8. 
Result so far: 87845.40978
If we subtract 5232 from 5620, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 14:
When dividing 3880 by 654, we get 5 with a remainder of 610.
Record the quotient 5 as the next digit in the result. 
Result so far: 87845.409785
If we subtract 3270 from 3880, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 15:
The number 654 fits into 6100 9 times, leaving a remainder of 214.
Record the quotient 9 as the next digit in the result. 
Result so far: 87845.4097859
Subtract 5886 from 6100 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 16:
2140 divided by 654 is 3 with a remainder of 178.
Use 3 as the next digit of our solution. 
Result so far: 87845.40978593
The remainder is 178 after subtracting 1962 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

The final outcome is 87845.40978593, with a leftover of 1.78e-07.
