We're dividing 88306690 by 407 
The aim is to understand the frequency of 407 in 88306690.

Step 1:
8 divided by 407 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 407

Let's proceed to step 2:
The number 407 fits into 88 0 times, leaving a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Fetch the next digit (3) from the dividend, attach it to 88 and continue: 883 / 407

On to step 3:
407 goes into 883 2 times with a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 814 away from 883, we end up with 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 407

Advancing to step 4:
407 goes into 690 1 times with a remainder of 283.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 407 from 690 and we're left with 283.
Fetch the next digit (6) from the dividend, attach it to 283 and continue: 2836 / 407

On to step 5:
2836 divided by 407 is 6 with a remainder of 394.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
Subtract 2442 from 2836 to get 394.
Grab the next digit (6) from the dividend, add it to 394, then carry on: 3946 / 407

Advancing to step 6:
If we divide 3946 by 407, we get 9 and a remainder of 283.
Use 9 as the next digit of our solution. 
Result so far: 2169.0
Subtracting 3663 from 3946 leaves us with 283.
Include the next digit (9) from the dividend after 283, then repeat: 2839 / 407

Let's proceed to step 7:
2839 divided by 407 is 6 with a remainder of 397.
The number 6 becomes the next digit in our result. 
Result so far: 21696.0
Deduct 2442 from 2839 and we're left with 397.
Grab the next digit (0) from the dividend, add it to 397, then carry on: 3970 / 407

On to step 8:
The number 407 fits into 3970 9 times, leaving a remainder of 307.
Put 9 as the next digit of the answer. 
Result so far: 216969.0
If we subtract 3663 from 3970, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 9:
When dividing 3070 by 407, we get 7 with a remainder of 221.
Write down 7 as next digit of the result. 
Result so far: 216969.7
Subtract 2849 from 3070 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 10:
The number 407 fits into 2210 5 times, leaving a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 216969.75
Subtracting 2035 from 2210 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
1750 divided by 407 is 4 with a remainder of 122.
Write down 4 as next digit of the result. 
Result so far: 216969.754
Deduct 1628 from 1750 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
The number 407 fits into 1220 2 times, leaving a remainder of 406.
Put 2 as the next digit of the answer. 
Result so far: 216969.7542
Subtract 814 from 1220 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 13:
If we divide 4060 by 407, we get 9 and a remainder of 397.
Write down 9 as next digit of the result. 
Result so far: 216969.75429
If we take 3663 away from 4060, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Moving on to step 14:
407 can be fit into 3970 9 times, resulting in a remainder of 307.
Record the quotient 9 as the next digit in the result. 
Result so far: 216969.754299
Deduct 3663 from 3970 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

The quotient of the division is 216969.754299, and the remainder is 3.07e-05.
