We look at the division of 99422790 by 597 
We want to divide 99422790 by 597.

Step 1:
9 divided by 597 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 597

Let's proceed to step 2:
If we divide 99 by 597, we get 0 and a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Take the next digit (4) from the dividend and append it to 99, then repeat: 994 / 597

On to step 3:
994 divided by 597 is 1 with a remainder of 397.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 597 from 994 to get 397.
Grab the next digit (2) from the dividend, add it to 397, then carry on: 3972 / 597

On to step 4:
When dividing 3972 by 597, we get 6 with a remainder of 390.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 3582 from 3972 to get 390.
Grab the next digit (2) from the dividend, add it to 390, then carry on: 3902 / 597

Let's proceed to step 5:
597 goes into 3902 6 times with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 166.0
Subtract 3582 from 3902 to get 320.
Take the next digit (7) from the dividend and append it to 320, then repeat: 3207 / 597

Moving on to step 6:
597 can be fit into 3207 5 times, resulting in a remainder of 222.
Put 5 as the next digit of the answer. 
Result so far: 1665.0
If we subtract 2985 from 3207, we get 222.
Append the next digit (9) from the dividend to 222 and continue with: 2229 / 597

Step 7:
2229 divided by 597 is 3 with a remainder of 438.
The number 3 becomes the next digit in our result. 
Result so far: 16653.0
If we take 1791 away from 2229, we end up with 438.
Grab the next digit (0) from the dividend, add it to 438, then carry on: 4380 / 597

Going ahead to step 8:
The number 597 fits into 4380 7 times, leaving a remainder of 201.
Record the quotient 7 as the next digit in the result. 
Result so far: 166537.0
Subtract 4179 from 4380 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
597 goes into 2010 3 times with a remainder of 219.
The number 3 becomes the next digit in our result. 
Result so far: 166537.3
Subtracting 1791 from 2010 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 10:
If we divide 2190 by 597, we get 3 and a remainder of 399.
The number 3 becomes the next digit in our result. 
Result so far: 166537.33
If we take 1791 away from 2190, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

After the division, we end up with 166537.33 and a remainder of 0.399.
