We divide 21100155 by 597
Our goal is to divide 21100155 by 597.

Moving on to step 1:
597 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 597

Step 2:
21 divided by 597 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 597

On to step 3:
If we divide 211 by 597, we get 0 and a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 597

Step 4:
If we divide 2110 by 597, we get 3 and a remainder of 319.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1791 from 2110 to get 319.
Fetch the next digit (0) from the dividend, attach it to 319 and continue: 3190 / 597

Moving on to step 5:
597 goes into 3190 5 times with a remainder of 205.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 2985 from 3190 to get 205.
Grab the next digit (1) from the dividend, add it to 205, then carry on: 2051 / 597

Step 6:
When dividing 2051 by 597, we get 3 with a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 353.0
If we subtract 1791 from 2051, we get 260.
Bring next digit (5) of the dividend behind the 260 and repeat the process: 2605 / 597

Advancing to step 7:
597 can be fit into 2605 4 times, resulting in a remainder of 217.
The number 4 becomes the next digit in our result. 
Result so far: 3534.0
Subtract 2388 from 2605 to get 217.
Fetch the next digit (5) from the dividend, attach it to 217 and continue: 2175 / 597

Let's proceed to step 8:
If we divide 2175 by 597, we get 3 and a remainder of 384.
The number 3 becomes the next digit in our result. 
Result so far: 35343.0
Deduct 1791 from 2175 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 9:
The number 597 fits into 3840 6 times, leaving a remainder of 258.
Write down 6 as next digit of the result. 
Result so far: 35343.6
Deduct 3582 from 3840 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 10:
If we divide 2580 by 597, we get 4 and a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 35343.64
The remainder is 192 after subtracting 2388 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 11:
When dividing 1920 by 597, we get 3 with a remainder of 129.
Put 3 as the next digit of the answer. 
Result so far: 35343.643
Subtracting 1791 from 1920 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
1290 divided by 597 is 2 with a remainder of 96.
The next digit of our result is 2. 
Result so far: 35343.6432
The remainder is 96 after subtracting 1194 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
When dividing 960 by 597, we get 1 with a remainder of 363.
Put 1 as the next digit of the answer. 
Result so far: 35343.64321
The remainder is 363 after subtracting 597 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 14:
597 goes into 3630 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 35343.643216
Deduct 3582 from 3630 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 15:
The number 597 fits into 480 0 times, leaving a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 35343.643216
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 16:
597 can be fit into 4800 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 35343.64321608
The remainder is 24 after subtracting 4776 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 35343.64321608, with a leftover of 2.4e-08.
