93869310 divided by 640 
The aim is to understand the frequency of 640 in 93869310.

Going ahead to step 1:
640 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 640

On to step 2:
640 can be fit into 93 0 times, resulting in a remainder of 93.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 93, we end up with 93.
Grab the next digit (8) from the dividend, add it to 93, then carry on: 938 / 640

Let's proceed to step 3:
The number 640 fits into 938 1 times, leaving a remainder of 298.
The next digit of our result is 1. 
Result so far: 1.0
If we take 640 away from 938, we end up with 298.
Take the next digit (6) from the dividend and append it to 298, then repeat: 2986 / 640

Advancing to step 4:
If we divide 2986 by 640, we get 4 and a remainder of 426.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 2560 from 2986 leaves us with 426.
Append the next digit (9) from the dividend to 426 and continue with: 4269 / 640

Going ahead to step 5:
4269 divided by 640 is 6 with a remainder of 429.
The next digit of our result is 6. 
Result so far: 146.0
Deduct 3840 from 4269 and we're left with 429.
Bring next digit (3) of the dividend behind the 429 and repeat the process: 4293 / 640

Moving on to step 6:
If we divide 4293 by 640, we get 6 and a remainder of 453.
Put 6 as the next digit of the answer. 
Result so far: 1466.0
The remainder is 453 after subtracting 3840 from 4293.
Fetch the next digit (1) from the dividend, attach it to 453 and continue: 4531 / 640

Moving on to step 7:
640 can be fit into 4531 7 times, resulting in a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 14667.0
Subtracting 4480 from 4531 leaves us with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 640

Going ahead to step 8:
The number 640 fits into 510 0 times, leaving a remainder of 510.
Write down 0 as next digit of the result. 
Result so far: 146670.0
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 9:
When dividing 5100 by 640, we get 7 with a remainder of 620.
The number 7 becomes the next digit in our result. 
Result so far: 146670.7
Subtract 4480 from 5100 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
The number 640 fits into 6200 9 times, leaving a remainder of 440.
The number 9 becomes the next digit in our result. 
Result so far: 146670.79
If we subtract 5760 from 6200, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
When dividing 4400 by 640, we get 6 with a remainder of 560.
Use 6 as the next digit of our solution. 
Result so far: 146670.796
Subtracting 3840 from 4400 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 12:
640 can be fit into 5600 8 times, resulting in a remainder of 480.
The next digit of our result is 8. 
Result so far: 146670.7968
If we subtract 5120 from 5600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
When dividing 4800 by 640, we get 7 with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 146670.79687
Subtract 4480 from 4800 to 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 14:
640 goes into 3200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 146670.796875
Deduct 3200 from 3200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 15:
640 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 146670.796875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 146670.796875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 146670.796875 and a remainder of 0.0.
