We look at the division of 60046479 by 490 
The aim is to understand the frequency of 490 in 60046479.

On to step 1:
If we divide 6 by 490, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 490

Let's proceed to step 2:
If we divide 60 by 490, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 490

Advancing to step 3:
If we divide 600 by 490, we get 1 and a remainder of 110.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 490 from 600 to get 110.
Grab the next digit (4) from the dividend, add it to 110, then carry on: 1104 / 490

Let's proceed to step 4:
1104 divided by 490 is 2 with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 980 from 1104 to get 124.
Grab the next digit (6) from the dividend, add it to 124, then carry on: 1246 / 490

On to step 5:
490 can be fit into 1246 2 times, resulting in a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtracting 980 from 1246 leaves us with 266.
Append the next digit (4) from the dividend to 266 and continue with: 2664 / 490

On to step 6:
490 can be fit into 2664 5 times, resulting in a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 1225.0
Subtract 2450 from 2664 to get 214.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 490

Advancing to step 7:
2147 divided by 490 is 4 with a remainder of 187.
Write down 4 as next digit of the result. 
Result so far: 12254.0
If we subtract 1960 from 2147, we get 187.
Append the next digit (9) from the dividend to 187 and continue with: 1879 / 490

Moving on to step 8:
The number 490 fits into 1879 3 times, leaving a remainder of 409.
The number 3 becomes the next digit in our result. 
Result so far: 122543.0
The remainder is 409 after subtracting 1470 from 1879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

On to step 9:
490 goes into 4090 8 times with a remainder of 170.
Use 8 as the next digit of our solution. 
Result so far: 122543.8
If we take 3920 away from 4090, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
490 goes into 1700 3 times with a remainder of 230.
Record the quotient 3 as the next digit in the result. 
Result so far: 122543.83
Subtract 1470 from 1700 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
490 goes into 2300 4 times with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 122543.834
If we subtract 1960 from 2300, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
The number 490 fits into 3400 6 times, leaving a remainder of 460.
The next digit of our result is 6. 
Result so far: 122543.8346
The remainder is 460 after subtracting 2940 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 13:
490 goes into 4600 9 times with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 122543.83469
Deduct 4410 from 4600 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 14:
1900 divided by 490 is 3 with a remainder of 430.
Write down 3 as next digit of the result. 
Result so far: 122543.834693
Deduct 1470 from 1900 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 15:
The number 490 fits into 4300 8 times, leaving a remainder of 380.
The next digit of our result is 8. 
Result so far: 122543.8346938
Subtract 3920 from 4300 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
If we divide 3800 by 490, we get 7 and a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 122543.83469387
Subtracting 3430 from 3800 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 122543.83469387, with a leftover of 3.7e-07.
