35551815 ÷ 161 
We want to figure out the number of times 35551815 can be divided by 161.

Let's proceed to step 1:
When dividing 3 by 161, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 161

Step 2:
35 divided by 161 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 161

Going ahead to step 3:
355 divided by 161 is 2 with a remainder of 33.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 33 after subtracting 322 from 355.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 161

On to step 4:
The number 161 fits into 335 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 322 from 335 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 161

Moving on to step 5:
If we divide 131 by 161, we get 0 and a remainder of 131.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
Deduct 0 from 131 and we're left with 131.
Append the next digit (8) from the dividend to 131 and continue with: 1318 / 161

Let's proceed to step 6:
1318 divided by 161 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 2208.0
Deduct 1288 from 1318 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 161

Moving on to step 7:
When dividing 301 by 161, we get 1 with a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 22081.0
Subtract 161 from 301 to get 140.
Take the next digit (5) from the dividend and append it to 140, then repeat: 1405 / 161

Going ahead to step 8:
161 goes into 1405 8 times with a remainder of 117.
Write down 8 as next digit of the result. 
Result so far: 220818.0
If we subtract 1288 from 1405, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 9:
The number 161 fits into 1170 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 220818.7
If we take 1127 away from 1170, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
When dividing 430 by 161, we get 2 with a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 220818.72
If we take 322 away from 430, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 11:
If we divide 1080 by 161, we get 6 and a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 220818.726
If we subtract 966 from 1080, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 12:
161 goes into 1140 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 220818.7267
Subtracting 1127 from 1140 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 13:
161 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 220818.7267
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
161 goes into 1300 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 220818.726708
If we take 1288 away from 1300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 15:
The number 161 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 220818.726708
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
If we divide 1200 by 161, we get 7 and a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 220818.72670807
Subtracting 1127 from 1200 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 220818.72670807, and the remainder is 7.3e-08.
