Let's divide 17215952 by 161
We want to figure out the number of times 17215952 can be divided by 161.

On to step 1:
The number 161 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 161

Advancing to step 2:
The number 161 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 161

Moving on to step 3:
When dividing 172 by 161, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 161 away from 172, we end up with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 161

Advancing to step 4:
The number 161 fits into 111 0 times, leaving a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 111, we end up with 111.
Take the next digit (5) from the dividend and append it to 111, then repeat: 1115 / 161

On to step 5:
The number 161 fits into 1115 6 times, leaving a remainder of 149.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 966 from 1115 and we're left with 149.
Take the next digit (9) from the dividend and append it to 149, then repeat: 1499 / 161

Let's proceed to step 6:
161 can be fit into 1499 9 times, resulting in a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 1069.0
Deduct 1449 from 1499 and we're left with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 161

Step 7:
When dividing 505 by 161, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 10693.0
The remainder is 22 after subtracting 483 from 505.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 161

Let's proceed to step 8:
If we divide 222 by 161, we get 1 and a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 106931.0
If we take 161 away from 222, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
If we divide 610 by 161, we get 3 and a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 106931.3
Subtracting 483 from 610 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 10:
161 goes into 1270 7 times with a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 106931.37
Deduct 1127 from 1270 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 11:
161 can be fit into 1430 8 times, resulting in a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 106931.378
Subtracting 1288 from 1430 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
161 can be fit into 1420 8 times, resulting in a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 106931.3788
Subtracting 1288 from 1420 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 106931.3788, with a leftover of 0.00132.
