We divide 40265441 by 643
The aim is to understand the frequency of 643 in 40265441.

Let's proceed to step 1:
If we divide 4 by 643, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 643

Moving on to step 2:
643 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 643

Step 3:
402 divided by 643 is 0 with a remainder of 402.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 402 and we're left with 402.
Grab the next digit (6) from the dividend, add it to 402, then carry on: 4026 / 643

Advancing to step 4:
643 goes into 4026 6 times with a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 3858 from 4026 and we're left with 168.
Append the next digit (5) from the dividend to 168 and continue with: 1685 / 643

Moving on to step 5:
643 can be fit into 1685 2 times, resulting in a remainder of 399.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 1286 from 1685, we get 399.
Fetch the next digit (4) from the dividend, attach it to 399 and continue: 3994 / 643

Moving on to step 6:
If we divide 3994 by 643, we get 6 and a remainder of 136.
Write down 6 as next digit of the result. 
Result so far: 626.0
The remainder is 136 after subtracting 3858 from 3994.
Take the next digit (4) from the dividend and append it to 136, then repeat: 1364 / 643

Step 7:
The number 643 fits into 1364 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 6262.0
Deduct 1286 from 1364 and we're left with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 643

Step 8:
If we divide 781 by 643, we get 1 and a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 62621.0
If we take 643 away from 781, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
643 goes into 1380 2 times with a remainder of 94.
Put 2 as the next digit of the answer. 
Result so far: 62621.2
Subtract 1286 from 1380 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
When dividing 940 by 643, we get 1 with a remainder of 297.
Put 1 as the next digit of the answer. 
Result so far: 62621.21
If we take 643 away from 940, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Step 11:
When dividing 2970 by 643, we get 4 with a remainder of 398.
Put 4 as the next digit of the answer. 
Result so far: 62621.214
If we subtract 2572 from 2970, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 12:
3980 divided by 643 is 6 with a remainder of 122.
Record the quotient 6 as the next digit in the result. 
Result so far: 62621.2146
Subtract 3858 from 3980 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 13:
643 can be fit into 1220 1 times, resulting in a remainder of 577.
The next digit of our result is 1. 
Result so far: 62621.21461
Subtract 643 from 1220 to get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Advancing to step 14:
643 goes into 5770 8 times with a remainder of 626.
Write down 8 as next digit of the result. 
Result so far: 62621.214618
Deduct 5144 from 5770 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 15:
When dividing 6260 by 643, we get 9 with a remainder of 473.
The next digit of our result is 9. 
Result so far: 62621.2146189
If we take 5787 away from 6260, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 16:
When dividing 4730 by 643, we get 7 with a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 62621.21461897
The remainder is 229 after subtracting 4501 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

The quotient of the division is 62621.21461897, and the remainder is 2.29e-07.
