87464799 divided by 620 
The aim is to understand the frequency of 620 in 87464799.

Moving on to step 1:
When dividing 8 by 620, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 620

On to step 2:
87 divided by 620 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (4) of the dividend behind the 87 and repeat the process: 874 / 620

Going ahead to step 3:
The number 620 fits into 874 1 times, leaving a remainder of 254.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 620 away from 874, we end up with 254.
Bring next digit (6) of the dividend behind the 254 and repeat the process: 2546 / 620

Let's proceed to step 4:
When dividing 2546 by 620, we get 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2480 from 2546, we get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 620

Step 5:
The number 620 fits into 664 1 times, leaving a remainder of 44.
The next digit of our result is 1. 
Result so far: 141.0
If we take 620 away from 664, we end up with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 620

Step 6:
620 goes into 447 0 times with a remainder of 447.
The number 0 becomes the next digit in our result. 
Result so far: 1410.0
If we subtract 0 from 447, we get 447.
Fetch the next digit (9) from the dividend, attach it to 447 and continue: 4479 / 620

Going ahead to step 7:
When dividing 4479 by 620, we get 7 with a remainder of 139.
Record the quotient 7 as the next digit in the result. 
Result so far: 14107.0
Subtracting 4340 from 4479 leaves us with 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 620

On to step 8:
1399 divided by 620 is 2 with a remainder of 159.
The number 2 becomes the next digit in our result. 
Result so far: 141072.0
Subtracting 1240 from 1399 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 9:
620 can be fit into 1590 2 times, resulting in a remainder of 350.
Record the quotient 2 as the next digit in the result. 
Result so far: 141072.2
Subtract 1240 from 1590 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 10:
When dividing 3500 by 620, we get 5 with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 141072.25
Deduct 3100 from 3500 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
When dividing 4000 by 620, we get 6 with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 141072.256
Subtract 3720 from 4000 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
When dividing 2800 by 620, we get 4 with a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 141072.2564
If we subtract 2480 from 2800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
The number 620 fits into 3200 5 times, leaving a remainder of 100.
The next digit of our result is 5. 
Result so far: 141072.25645
Subtract 3100 from 3200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
When dividing 1000 by 620, we get 1 with a remainder of 380.
Use 1 as the next digit of our solution. 
Result so far: 141072.256451
Subtract 620 from 1000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
620 goes into 3800 6 times with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 141072.2564516
Deduct 3720 from 3800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
The number 620 fits into 800 1 times, leaving a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 141072.25645161
Subtracting 620 from 800 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 141072.25645161, and the remainder is 1.8e-07.
