61574455 ÷ 164 
We're looking to find how many times 164 goes into 61574455.

Going ahead to step 1:
The number 164 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 164

Going ahead to step 2:
164 can be fit into 61 0 times, resulting in a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 164

Step 3:
If we divide 615 by 164, we get 3 and a remainder of 123.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 492 from 615, we get 123.
Bring next digit (7) of the dividend behind the 123 and repeat the process: 1237 / 164

Advancing to step 4:
The number 164 fits into 1237 7 times, leaving a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 1148 from 1237 to get 89.
Include the next digit (4) from the dividend after 89, then repeat: 894 / 164

Step 5:
If we divide 894 by 164, we get 5 and a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 375.0
The remainder is 74 after subtracting 820 from 894.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 164

Moving on to step 6:
The number 164 fits into 744 4 times, leaving a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 3754.0
Deduct 656 from 744 and we're left with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 164

Going ahead to step 7:
The number 164 fits into 885 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 37545.0
If we take 820 away from 885, we end up with 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 164

Going ahead to step 8:
If we divide 655 by 164, we get 3 and a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 375453.0
Deduct 492 from 655 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 9:
If we divide 1630 by 164, we get 9 and a remainder of 154.
Record the quotient 9 as the next digit in the result. 
Result so far: 375453.9
Subtract 1476 from 1630 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
164 goes into 1540 9 times with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 375453.99
If we take 1476 away from 1540, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 375453.99, with a leftover of 0.064.
