73891941 divided by 731 
The aim is to understand the frequency of 731 in 73891941.

Let's proceed to step 1:
731 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 731

Step 2:
If we divide 73 by 731, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 731

Going ahead to step 3:
738 divided by 731 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 731 from 738 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 731

Going ahead to step 4:
The number 731 fits into 79 0 times, leaving a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 79 to get 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 731

Advancing to step 5:
731 can be fit into 791 1 times, resulting in a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtracting 731 from 791 leaves us with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 731

Let's proceed to step 6:
When dividing 609 by 731, we get 0 with a remainder of 609.
Use 0 as the next digit of our solution. 
Result so far: 1010.0
Subtract 0 from 609 to get 609.
Bring next digit (4) of the dividend behind the 609 and repeat the process: 6094 / 731

Advancing to step 7:
When dividing 6094 by 731, we get 8 with a remainder of 246.
The number 8 becomes the next digit in our result. 
Result so far: 10108.0
Subtract 5848 from 6094 to get 246.
Grab the next digit (1) from the dividend, add it to 246, then carry on: 2461 / 731

Moving on to step 8:
731 goes into 2461 3 times with a remainder of 268.
Use 3 as the next digit of our solution. 
Result so far: 101083.0
Subtracting 2193 from 2461 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 9:
731 can be fit into 2680 3 times, resulting in a remainder of 487.
The number 3 becomes the next digit in our result. 
Result so far: 101083.3
If we take 2193 away from 2680, we end up with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Step 10:
731 can be fit into 4870 6 times, resulting in a remainder of 484.
Write down 6 as next digit of the result. 
Result so far: 101083.36
The remainder is 484 after subtracting 4386 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 11:
4840 divided by 731 is 6 with a remainder of 454.
The next digit of our result is 6. 
Result so far: 101083.366
If we take 4386 away from 4840, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Our division results in 101083.366 with a remaining 0.0454.
