77900789 ÷ 912 
The aim is to understand the frequency of 912 in 77900789.

Moving on to step 1:
The number 912 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 912

On to step 2:
When dividing 77 by 912, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 912

Advancing to step 3:
912 can be fit into 779 0 times, resulting in a remainder of 779.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 779 to get 779.
Include the next digit (0) from the dividend after 779, then repeat: 7790 / 912

Let's proceed to step 4:
The number 912 fits into 7790 8 times, leaving a remainder of 494.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 494 after subtracting 7296 from 7790.
Include the next digit (0) from the dividend after 494, then repeat: 4940 / 912

On to step 5:
912 goes into 4940 5 times with a remainder of 380.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtracting 4560 from 4940 leaves us with 380.
Include the next digit (7) from the dividend after 380, then repeat: 3807 / 912

Moving on to step 6:
When dividing 3807 by 912, we get 4 with a remainder of 159.
Use 4 as the next digit of our solution. 
Result so far: 854.0
If we take 3648 away from 3807, we end up with 159.
Grab the next digit (8) from the dividend, add it to 159, then carry on: 1598 / 912

Advancing to step 7:
1598 divided by 912 is 1 with a remainder of 686.
Write down 1 as next digit of the result. 
Result so far: 8541.0
Deduct 912 from 1598 and we're left with 686.
Append the next digit (9) from the dividend to 686 and continue with: 6869 / 912

Advancing to step 8:
6869 divided by 912 is 7 with a remainder of 485.
Use 7 as the next digit of our solution. 
Result so far: 85417.0
Subtract 6384 from 6869 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 9:
4850 divided by 912 is 5 with a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 85417.5
If we subtract 4560 from 4850, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
2900 divided by 912 is 3 with a remainder of 164.
The next digit of our result is 3. 
Result so far: 85417.53
Deduct 2736 from 2900 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
If we divide 1640 by 912, we get 1 and a remainder of 728.
Record the quotient 1 as the next digit in the result. 
Result so far: 85417.531
Subtracting 912 from 1640 leaves us with 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Let's proceed to step 12:
912 can be fit into 7280 7 times, resulting in a remainder of 896.
Record the quotient 7 as the next digit in the result. 
Result so far: 85417.5317
If we subtract 6384 from 7280, we get 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8960, and continue the process.

Moving on to step 13:
The number 912 fits into 8960 9 times, leaving a remainder of 752.
Write down 9 as next digit of the result. 
Result so far: 85417.53179
If we take 8208 away from 8960, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Moving on to step 14:
912 can be fit into 7520 8 times, resulting in a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 85417.531798
If we subtract 7296 from 7520, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 15:
If we divide 2240 by 912, we get 2 and a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 85417.5317982
If we take 1824 away from 2240, 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 16:
The number 912 fits into 4160 4 times, leaving a remainder of 512.
Put 4 as the next digit of the answer. 
Result so far: 85417.53179824
If we take 3648 away from 4160, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 85417.53179824 with a remaining 5.12e-07.
