55422869 ÷ 355 
Our goal is to divide 55422869 by 355.

Advancing to step 1:
When dividing 5 by 355, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 355

Going ahead to step 2:
355 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 355

Step 3:
If we divide 554 by 355, we get 1 and a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 355 from 554 leaves us with 199.
Grab the next digit (2) from the dividend, add it to 199, then carry on: 1992 / 355

Going ahead to step 4:
355 goes into 1992 5 times with a remainder of 217.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1775 from 1992 leaves us with 217.
Bring next digit (2) of the dividend behind the 217 and repeat the process: 2172 / 355

Advancing to step 5:
2172 divided by 355 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we take 2130 away from 2172, we end up with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 355

Step 6:
If we divide 428 by 355, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 1561.0
If we take 355 away from 428, we end up with 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 355

Step 7:
355 goes into 736 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 15612.0
If we take 710 away from 736, we end up with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 355

On to step 8:
355 can be fit into 269 0 times, resulting in a remainder of 269.
The next digit of our result is 0. 
Result so far: 156120.0
Subtracting 0 from 269 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 9:
355 can be fit into 2690 7 times, resulting in a remainder of 205.
Write down 7 as next digit of the result. 
Result so far: 156120.7
If we subtract 2485 from 2690, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 10:
When dividing 2050 by 355, we get 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 156120.75
If we take 1775 away from 2050, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 11:
When dividing 2750 by 355, we get 7 with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 156120.757
Subtract 2485 from 2750 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 12:
If we divide 2650 by 355, we get 7 and a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 156120.7577
Subtract 2485 from 2650 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final outcome is 156120.7577, with a leftover of 0.00165.
