83970772 divided by 598 
The aim is to understand the frequency of 598 in 83970772.

Going ahead to step 1:
The number 598 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 598

Step 2:
The number 598 fits into 83 0 times, leaving a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 598

Advancing to step 3:
The number 598 fits into 839 1 times, leaving a remainder of 241.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 598 from 839 to get 241.
Include the next digit (7) from the dividend after 241, then repeat: 2417 / 598

On to step 4:
When dividing 2417 by 598, we get 4 with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2392 from 2417, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 598

Step 5:
598 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 140.0
Deduct 0 from 250 and we're left with 250.
Fetch the next digit (7) from the dividend, attach it to 250 and continue: 2507 / 598

Step 6:
The number 598 fits into 2507 4 times, leaving a remainder of 115.
Write down 4 as next digit of the result. 
Result so far: 1404.0
Deduct 2392 from 2507 and we're left with 115.
Fetch the next digit (7) from the dividend, attach it to 115 and continue: 1157 / 598

On to step 7:
If we divide 1157 by 598, we get 1 and a remainder of 559.
Write down 1 as next digit of the result. 
Result so far: 14041.0
If we take 598 away from 1157, we end up with 559.
Grab the next digit (2) from the dividend, add it to 559, then carry on: 5592 / 598

Going ahead to step 8:
If we divide 5592 by 598, we get 9 and a remainder of 210.
Record the quotient 9 as the next digit in the result. 
Result so far: 140419.0
Subtracting 5382 from 5592 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 9:
When dividing 2100 by 598, we get 3 with a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 140419.3
Subtract 1794 from 2100 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 10:
3060 divided by 598 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 140419.35
Subtract 2990 from 3060 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
When dividing 700 by 598, we get 1 with a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 140419.351
Subtracting 598 from 700 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 12:
When dividing 1020 by 598, we get 1 with a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 140419.3511
If we subtract 598 from 1020, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

The quotient of the division is 140419.3511, and the remainder is 0.00422.
