90583688 divided by 702 
The aim is to understand the frequency of 702 in 90583688.

On to step 1:
9 divided by 702 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 702

Moving on to step 2:
702 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 702

Step 3:
702 can be fit into 905 1 times, resulting in a remainder of 203.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 203 after subtracting 702 from 905.
Bring next digit (8) of the dividend behind the 203 and repeat the process: 2038 / 702

Step 4:
The number 702 fits into 2038 2 times, leaving a remainder of 634.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1404 away from 2038, we end up with 634.
Bring next digit (3) of the dividend behind the 634 and repeat the process: 6343 / 702

Step 5:
6343 divided by 702 is 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 129.0
Deduct 6318 from 6343 and we're left with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 702

On to step 6:
702 goes into 256 0 times with a remainder of 256.
Record the quotient 0 as the next digit in the result. 
Result so far: 1290.0
If we subtract 0 from 256, we get 256.
Fetch the next digit (8) from the dividend, attach it to 256 and continue: 2568 / 702

On to step 7:
If we divide 2568 by 702, we get 3 and a remainder of 462.
Record the quotient 3 as the next digit in the result. 
Result so far: 12903.0
The remainder is 462 after subtracting 2106 from 2568.
Append the next digit (8) from the dividend to 462 and continue with: 4628 / 702

Going ahead to step 8:
If we divide 4628 by 702, we get 6 and a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 129036.0
If we subtract 4212 from 4628, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 9:
When dividing 4160 by 702, we get 5 with a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 129036.5
Subtracting 3510 from 4160 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 10:
If we divide 6500 by 702, we get 9 and a remainder of 182.
Use 9 as the next digit of our solution. 
Result so far: 129036.59
The remainder is 182 after subtracting 6318 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 11:
If we divide 1820 by 702, we get 2 and a remainder of 416.
Use 2 as the next digit of our solution. 
Result so far: 129036.592
If we subtract 1404 from 1820, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 12:
702 goes into 4160 5 times with a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 129036.5925
If we subtract 3510 from 4160, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 13:
6500 divided by 702 is 9 with a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 129036.59259
Subtracting 6318 from 6500 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 14:
The number 702 fits into 1820 2 times, leaving a remainder of 416.
The next digit of our result is 2. 
Result so far: 129036.592592
Subtract 1404 from 1820 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 15:
If we divide 4160 by 702, we get 5 and a remainder of 650.
Put 5 as the next digit of the answer. 
Result so far: 129036.5925925
Deduct 3510 from 4160 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 16:
If we divide 6500 by 702, we get 9 and a remainder of 182.
Record the quotient 9 as the next digit in the result. 
Result so far: 129036.59259259
Deduct 6318 from 6500 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 129036.59259259 and a remainder of 1.82e-07.
