Let's divide 55900083 by 643
The aim is to understand the frequency of 643 in 55900083.

Step 1:
643 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 643

On to step 2:
55 divided by 643 is 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 643

Going ahead to step 3:
When dividing 559 by 643, we get 0 with a remainder of 559.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 559, we get 559.
Grab the next digit (0) from the dividend, add it to 559, then carry on: 5590 / 643

On to step 4:
If we divide 5590 by 643, we get 8 and a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 446 after subtracting 5144 from 5590.
Bring next digit (0) of the dividend behind the 446 and repeat the process: 4460 / 643

Let's proceed to step 5:
The number 643 fits into 4460 6 times, leaving a remainder of 602.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Deduct 3858 from 4460 and we're left with 602.
Append the next digit (0) from the dividend to 602 and continue with: 6020 / 643

Step 6:
The number 643 fits into 6020 9 times, leaving a remainder of 233.
Put 9 as the next digit of the answer. 
Result so far: 869.0
If we take 5787 away from 6020, we end up with 233.
Take the next digit (8) from the dividend and append it to 233, then repeat: 2338 / 643

Let's proceed to step 7:
643 goes into 2338 3 times with a remainder of 409.
Put 3 as the next digit of the answer. 
Result so far: 8693.0
If we subtract 1929 from 2338, we get 409.
Take the next digit (3) from the dividend and append it to 409, then repeat: 4093 / 643

Moving on to step 8:
The number 643 fits into 4093 6 times, leaving a remainder of 235.
Use 6 as the next digit of our solution. 
Result so far: 86936.0
Subtracting 3858 from 4093 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 9:
The number 643 fits into 2350 3 times, leaving a remainder of 421.
Use 3 as the next digit of our solution. 
Result so far: 86936.3
Subtracting 1929 from 2350 leaves us with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Let's proceed to step 10:
4210 divided by 643 is 6 with a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 86936.36
The remainder is 352 after subtracting 3858 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 11:
3520 divided by 643 is 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 86936.365
Deduct 3215 from 3520 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 12:
If we divide 3050 by 643, we get 4 and a remainder of 478.
Write down 4 as next digit of the result. 
Result so far: 86936.3654
If we take 2572 away from 3050, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 13:
4780 divided by 643 is 7 with a remainder of 279.
Write down 7 as next digit of the result. 
Result so far: 86936.36547
Subtract 4501 from 4780 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 14:
When dividing 2790 by 643, we get 4 with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 86936.365474
If we subtract 2572 from 2790, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
2180 divided by 643 is 3 with a remainder of 251.
The next digit of our result is 3. 
Result so far: 86936.3654743
Subtract 1929 from 2180 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 16:
If we divide 2510 by 643, we get 3 and a remainder of 581.
The number 3 becomes the next digit in our result. 
Result so far: 86936.36547433
If we subtract 1929 from 2510, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

The quotient of the division is 86936.36547433, and the remainder is 5.81e-07.
