We're dividing 77787029 by 598 
The aim is to understand the frequency of 598 in 77787029.

Going ahead to step 1:
598 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 598

Moving on to step 2:
When dividing 77 by 598, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 598

Going ahead to step 3:
598 goes into 777 1 times with a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 598 from 777 and we're left with 179.
Bring next digit (8) of the dividend behind the 179 and repeat the process: 1798 / 598

Advancing to step 4:
When dividing 1798 by 598, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 4 after subtracting 1794 from 1798.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 598

Advancing to step 5:
The number 598 fits into 47 0 times, leaving a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Deduct 0 from 47 and we're left with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 598

Advancing to step 6:
598 goes into 470 0 times with a remainder of 470.
Use 0 as the next digit of our solution. 
Result so far: 1300.0
Subtract 0 from 470 to get 470.
Grab the next digit (2) from the dividend, add it to 470, then carry on: 4702 / 598

Advancing to step 7:
If we divide 4702 by 598, we get 7 and a remainder of 516.
The number 7 becomes the next digit in our result. 
Result so far: 13007.0
Deduct 4186 from 4702 and we're left with 516.
Fetch the next digit (9) from the dividend, attach it to 516 and continue: 5169 / 598

Moving on to step 8:
5169 divided by 598 is 8 with a remainder of 385.
The next digit of our result is 8. 
Result so far: 130078.0
Subtract 4784 from 5169 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 9:
598 goes into 3850 6 times with a remainder of 262.
Write down 6 as next digit of the result. 
Result so far: 130078.6
Deduct 3588 from 3850 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 10:
598 goes into 2620 4 times with a remainder of 228.
Use 4 as the next digit of our solution. 
Result so far: 130078.64
Deduct 2392 from 2620 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 11:
If we divide 2280 by 598, we get 3 and a remainder of 486.
The number 3 becomes the next digit in our result. 
Result so far: 130078.643
If we subtract 1794 from 2280, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 12:
598 goes into 4860 8 times with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 130078.6438
Deduct 4784 from 4860 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
If we divide 760 by 598, we get 1 and a remainder of 162.
The next digit of our result is 1. 
Result so far: 130078.64381
If we subtract 598 from 760, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 14:
1620 divided by 598 is 2 with a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 130078.643812
If we take 1196 away from 1620, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 15:
The number 598 fits into 4240 7 times, leaving a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 130078.6438127
Deduct 4186 from 4240 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 16:
598 can be fit into 540 0 times, resulting in a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 130078.6438127
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final result is 130078.6438127 with a remainder of 5.4e-07.
