We divide 40098563 by 605
The aim is to understand the frequency of 605 in 40098563.

Step 1:
If we divide 4 by 605, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 605

Let's proceed to step 2:
The number 605 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 605

Moving on to step 3:
605 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Append the next digit (9) from the dividend to 400 and continue with: 4009 / 605

On to step 4:
The number 605 fits into 4009 6 times, leaving a remainder of 379.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 3630 from 4009, we get 379.
Bring next digit (8) of the dividend behind the 379 and repeat the process: 3798 / 605

Advancing to step 5:
3798 divided by 605 is 6 with a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 168 after subtracting 3630 from 3798.
Fetch the next digit (5) from the dividend, attach it to 168 and continue: 1685 / 605

Going ahead to step 6:
If we divide 1685 by 605, we get 2 and a remainder of 475.
The number 2 becomes the next digit in our result. 
Result so far: 662.0
The remainder is 475 after subtracting 1210 from 1685.
Grab the next digit (6) from the dividend, add it to 475, then carry on: 4756 / 605

Going ahead to step 7:
When dividing 4756 by 605, we get 7 with a remainder of 521.
The number 7 becomes the next digit in our result. 
Result so far: 6627.0
If we take 4235 away from 4756, we end up with 521.
Include the next digit (3) from the dividend after 521, then repeat: 5213 / 605

On to step 8:
When dividing 5213 by 605, we get 8 with a remainder of 373.
The next digit of our result is 8. 
Result so far: 66278.0
Subtracting 4840 from 5213 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 9:
When dividing 3730 by 605, we get 6 with a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 66278.6
The remainder is 100 after subtracting 3630 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
605 can be fit into 1000 1 times, resulting in a remainder of 395.
The number 1 becomes the next digit in our result. 
Result so far: 66278.61
If we take 605 away from 1000, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 11:
When dividing 3950 by 605, we get 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 66278.616
Deduct 3630 from 3950 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 12:
605 can be fit into 3200 5 times, resulting in a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 66278.6165
Subtract 3025 from 3200 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
When dividing 1750 by 605, we get 2 with a remainder of 540.
Use 2 as the next digit of our solution. 
Result so far: 66278.61652
If we subtract 1210 from 1750, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 14:
The number 605 fits into 5400 8 times, leaving a remainder of 560.
The next digit of our result is 8. 
Result so far: 66278.616528
Deduct 4840 from 5400 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 15:
5600 divided by 605 is 9 with a remainder of 155.
Use 9 as the next digit of our solution. 
Result so far: 66278.6165289
If we take 5445 away from 5600, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 16:
1550 divided by 605 is 2 with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 66278.61652892
If we subtract 1210 from 1550, 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.

Our division results in 66278.61652892 with a remaining 3.4e-07.
