We divide 38071977 by 643
The aim is to understand the frequency of 643 in 38071977.

Step 1:
3 divided by 643 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 643

Let's proceed to step 2:
If we divide 38 by 643, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 643

Advancing to step 3:
If we divide 380 by 643, we get 0 and a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 380 to get 380.
Grab the next digit (7) from the dividend, add it to 380, then carry on: 3807 / 643

Let's proceed to step 4:
When dividing 3807 by 643, we get 5 with a remainder of 592.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3215 from 3807 to get 592.
Include the next digit (1) from the dividend after 592, then repeat: 5921 / 643

Going ahead to step 5:
643 goes into 5921 9 times with a remainder of 134.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 5787 from 5921, we get 134.
Bring next digit (9) of the dividend behind the 134 and repeat the process: 1349 / 643

Going ahead to step 6:
The number 643 fits into 1349 2 times, leaving a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 592.0
If we take 1286 away from 1349, we end up with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 643

Advancing to step 7:
643 can be fit into 637 0 times, resulting in a remainder of 637.
Record the quotient 0 as the next digit in the result. 
Result so far: 5920.0
Subtract 0 from 637 to get 637.
Include the next digit (7) from the dividend after 637, then repeat: 6377 / 643

Moving on to step 8:
6377 divided by 643 is 9 with a remainder of 590.
The next digit of our result is 9. 
Result so far: 59209.0
The remainder is 590 after subtracting 5787 from 6377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 9:
643 can be fit into 5900 9 times, resulting in a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 59209.9
Subtracting 5787 from 5900 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 10:
If we divide 1130 by 643, we get 1 and a remainder of 487.
The next digit of our result is 1. 
Result so far: 59209.91
Subtract 643 from 1130 to get 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Advancing to step 11:
4870 divided by 643 is 7 with a remainder of 369.
Use 7 as the next digit of our solution. 
Result so far: 59209.917
Subtract 4501 from 4870 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Let's proceed to step 12:
643 can be fit into 3690 5 times, resulting in a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 59209.9175
Subtract 3215 from 3690 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 13:
4750 divided by 643 is 7 with a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 59209.91757
Subtracting 4501 from 4750 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 14:
When dividing 2490 by 643, we get 3 with a remainder of 561.
Record the quotient 3 as the next digit in the result. 
Result so far: 59209.917573
If we subtract 1929 from 2490, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Let's proceed to step 15:
If we divide 5610 by 643, we get 8 and a remainder of 466.
Put 8 as the next digit of the answer. 
Result so far: 59209.9175738
If we take 5144 away from 5610, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 16:
The number 643 fits into 4660 7 times, leaving a remainder of 159.
Record the quotient 7 as the next digit in the result. 
Result so far: 59209.91757387
The remainder is 159 after subtracting 4501 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Our division results in 59209.91757387 with a remaining 1.59e-07.
