78270011 ÷ 902 
The aim is to understand the frequency of 902 in 78270011.

Advancing to step 1:
If we divide 7 by 902, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 902

Let's proceed to step 2:
When dividing 78 by 902, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 902

On to step 3:
782 divided by 902 is 0 with a remainder of 782.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 782 to get 782.
Bring next digit (7) of the dividend behind the 782 and repeat the process: 7827 / 902

On to step 4:
If we divide 7827 by 902, we get 8 and a remainder of 611.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7216 away from 7827, we end up with 611.
Take the next digit (0) from the dividend and append it to 611, then repeat: 6110 / 902

Moving on to step 5:
If we divide 6110 by 902, we get 6 and a remainder of 698.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 5412 from 6110, we get 698.
Take the next digit (0) from the dividend and append it to 698, then repeat: 6980 / 902

Advancing to step 6:
902 can be fit into 6980 7 times, resulting in a remainder of 666.
The next digit of our result is 7. 
Result so far: 867.0
If we take 6314 away from 6980, we end up with 666.
Bring next digit (1) of the dividend behind the 666 and repeat the process: 6661 / 902

Going ahead to step 7:
902 goes into 6661 7 times with a remainder of 347.
Record the quotient 7 as the next digit in the result. 
Result so far: 8677.0
Deduct 6314 from 6661 and we're left with 347.
Grab the next digit (1) from the dividend, add it to 347, then carry on: 3471 / 902

Advancing to step 8:
The number 902 fits into 3471 3 times, leaving a remainder of 765.
Record the quotient 3 as the next digit in the result. 
Result so far: 86773.0
If we take 2706 away from 3471, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Going ahead to step 9:
When dividing 7650 by 902, we get 8 with a remainder of 434.
The next digit of our result is 8. 
Result so far: 86773.8
Subtract 7216 from 7650 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 10:
If we divide 4340 by 902, we get 4 and a remainder of 732.
Record the quotient 4 as the next digit in the result. 
Result so far: 86773.84
Subtract 3608 from 4340 to get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Step 11:
902 can be fit into 7320 8 times, resulting in a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 86773.848
Subtract 7216 from 7320 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
The number 902 fits into 1040 1 times, leaving a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 86773.8481
Subtracting 902 from 1040 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 13:
1380 divided by 902 is 1 with a remainder of 478.
Put 1 as the next digit of the answer. 
Result so far: 86773.84811
Subtracting 902 from 1380 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Our division results in 86773.84811 with a remaining 0.000478.
