We look at the division of 99970020 by 355 
We're looking to find how many times 355 goes into 99970020.

Advancing to step 1:
If we divide 9 by 355, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 355

Moving on to step 2:
99 divided by 355 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 355

On to step 3:
The number 355 fits into 999 2 times, leaving a remainder of 289.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 710 from 999, we get 289.
Bring next digit (7) of the dividend behind the 289 and repeat the process: 2897 / 355

Advancing to step 4:
The number 355 fits into 2897 8 times, leaving a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 2840 from 2897 and we're left with 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 355

Going ahead to step 5:
355 goes into 570 1 times with a remainder of 215.
The number 1 becomes the next digit in our result. 
Result so far: 281.0
Subtracting 355 from 570 leaves us with 215.
Fetch the next digit (0) from the dividend, attach it to 215 and continue: 2150 / 355

Advancing to step 6:
When dividing 2150 by 355, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 2816.0
The remainder is 20 after subtracting 2130 from 2150.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 355

On to step 7:
355 can be fit into 202 0 times, resulting in a remainder of 202.
The number 0 becomes the next digit in our result. 
Result so far: 28160.0
Subtracting 0 from 202 leaves us with 202.
Grab the next digit (0) from the dividend, add it to 202, then carry on: 2020 / 355

Let's proceed to step 8:
355 can be fit into 2020 5 times, resulting in a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 281605.0
If we subtract 1775 from 2020, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 9:
355 goes into 2450 6 times with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 281605.6
Subtracting 2130 from 2450 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
When dividing 3200 by 355, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 281605.69
The remainder is 5 after subtracting 3195 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
50 divided by 355 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 281605.69
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
If we divide 500 by 355, we get 1 and a remainder of 145.
The next digit of our result is 1. 
Result so far: 281605.6901
If we take 355 away from 500, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 13:
355 can be fit into 1450 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 281605.69014
Subtracting 1420 from 1450 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
The number 355 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 281605.69014
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
355 goes into 3000 8 times with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 281605.6901408
Subtracting 2840 from 3000 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
355 goes into 1600 4 times with a remainder of 180.
Write down 4 as next digit of the result. 
Result so far: 281605.69014084
Subtract 1420 from 1600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 281605.69014084, with a leftover of 1.8e-07.
