89081801 ÷ 777 
The aim is to understand the frequency of 777 in 89081801.

Going ahead to step 1:
777 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 777

Going ahead to step 2:
777 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 777

Moving on to step 3:
890 divided by 777 is 1 with a remainder of 113.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 777 away from 890, we end up with 113.
Take the next digit (8) from the dividend and append it to 113, then repeat: 1138 / 777

Advancing to step 4:
The number 777 fits into 1138 1 times, leaving a remainder of 361.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 777 from 1138 to get 361.
Take the next digit (1) from the dividend and append it to 361, then repeat: 3611 / 777

Advancing to step 5:
If we divide 3611 by 777, we get 4 and a remainder of 503.
Put 4 as the next digit of the answer. 
Result so far: 114.0
The remainder is 503 after subtracting 3108 from 3611.
Append the next digit (8) from the dividend to 503 and continue with: 5038 / 777

Let's proceed to step 6:
When dividing 5038 by 777, we get 6 with a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 1146.0
Deduct 4662 from 5038 and we're left with 376.
Append the next digit (0) from the dividend to 376 and continue with: 3760 / 777

Advancing to step 7:
The number 777 fits into 3760 4 times, leaving a remainder of 652.
Use 4 as the next digit of our solution. 
Result so far: 11464.0
The remainder is 652 after subtracting 3108 from 3760.
Grab the next digit (1) from the dividend, add it to 652, then carry on: 6521 / 777

Let's proceed to step 8:
777 goes into 6521 8 times with a remainder of 305.
Record the quotient 8 as the next digit in the result. 
Result so far: 114648.0
Subtracting 6216 from 6521 leaves us with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 9:
If we divide 3050 by 777, we get 3 and a remainder of 719.
The next digit of our result is 3. 
Result so far: 114648.3
Subtracting 2331 from 3050 leaves us with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Moving on to step 10:
777 can be fit into 7190 9 times, resulting in a remainder of 197.
Record the quotient 9 as the next digit in the result. 
Result so far: 114648.39
Subtract 6993 from 7190 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 11:
777 goes into 1970 2 times with a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 114648.392
If we take 1554 away from 1970, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 12:
4160 divided by 777 is 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 114648.3925
If we take 3885 away from 4160, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 13:
If we divide 2750 by 777, we get 3 and a remainder of 419.
Record the quotient 3 as the next digit in the result. 
Result so far: 114648.39253
If we subtract 2331 from 2750, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

On to step 14:
If we divide 4190 by 777, we get 5 and a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 114648.392535
If we take 3885 away from 4190, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 15:
3050 divided by 777 is 3 with a remainder of 719.
Write down 3 as next digit of the result. 
Result so far: 114648.3925353
The remainder is 719 after subtracting 2331 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Advancing to step 16:
When dividing 7190 by 777, we get 9 with a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 114648.39253539
Deduct 6993 from 7190 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final outcome is 114648.39253539, with a leftover of 1.97e-07.
