Let's divide 71938701 by 486
The aim is to understand the frequency of 486 in 71938701.

On to step 1:
When dividing 7 by 486, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 486

Let's proceed to step 2:
If we divide 71 by 486, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 486

Let's proceed to step 3:
486 goes into 719 1 times with a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 233 after subtracting 486 from 719.
Fetch the next digit (3) from the dividend, attach it to 233 and continue: 2333 / 486

Going ahead to step 4:
When dividing 2333 by 486, we get 4 with a remainder of 389.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1944 away from 2333, we end up with 389.
Fetch the next digit (8) from the dividend, attach it to 389 and continue: 3898 / 486

Let's proceed to step 5:
486 can be fit into 3898 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 148.0
The remainder is 10 after subtracting 3888 from 3898.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 486

Advancing to step 6:
The number 486 fits into 107 0 times, leaving a remainder of 107.
The next digit of our result is 0. 
Result so far: 1480.0
If we take 0 away from 107, we end up with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 486

Let's proceed to step 7:
When dividing 1070 by 486, we get 2 with a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 14802.0
If we take 972 away from 1070, we end up with 98.
Take the next digit (1) from the dividend and append it to 98, then repeat: 981 / 486

Step 8:
When dividing 981 by 486, we get 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 148022.0
If we subtract 972 from 981, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 486, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 148022.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
900 divided by 486 is 1 with a remainder of 414.
Put 1 as the next digit of the answer. 
Result so far: 148022.01
Subtract 486 from 900 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 11:
4140 divided by 486 is 8 with a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 148022.018
Deduct 3888 from 4140 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 12:
The number 486 fits into 2520 5 times, leaving a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 148022.0185
If we take 2430 away from 2520, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
When dividing 900 by 486, we get 1 with a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 148022.01851
If we take 486 away from 900, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 14:
The number 486 fits into 4140 8 times, leaving a remainder of 252.
Record the quotient 8 as the next digit in the result. 
Result so far: 148022.018518
The remainder is 252 after subtracting 3888 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 15:
The number 486 fits into 2520 5 times, leaving a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 148022.0185185
If we subtract 2430 from 2520, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 16:
486 can be fit into 900 1 times, resulting in a remainder of 414.
Use 1 as the next digit of our solution. 
Result so far: 148022.01851851
Subtracting 486 from 900 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

The quotient of the division is 148022.01851851, and the remainder is 4.14e-07.
