We're dividing 90743089 by 161 
We're looking to find how many times 161 goes into 90743089.

On to step 1:
161 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 161

Going ahead to step 2:
The number 161 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (7) from the dividend after 90, then repeat: 907 / 161

On to step 3:
If we divide 907 by 161, we get 5 and a remainder of 102.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 805 from 907 and we're left with 102.
Grab the next digit (4) from the dividend, add it to 102, then carry on: 1024 / 161

Going ahead to step 4:
161 can be fit into 1024 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 966 from 1024 and we're left with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 161

On to step 5:
The number 161 fits into 583 3 times, leaving a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 563.0
If we take 483 away from 583, we end up with 100.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 161

Step 6:
If we divide 1000 by 161, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 5636.0
Subtracting 966 from 1000 leaves us with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 161

Going ahead to step 7:
161 goes into 348 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 56362.0
If we subtract 322 from 348, we get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 161

Step 8:
When dividing 269 by 161, we get 1 with a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 563621.0
Subtracting 161 from 269 leaves us 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.

On to step 9:
When dividing 1080 by 161, we get 6 with a remainder of 114.
The next digit of our result is 6. 
Result so far: 563621.6
Subtracting 966 from 1080 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
161 goes into 1140 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 563621.67
Subtract 1127 from 1140 to get 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 11:
When dividing 130 by 161, we get 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 563621.67
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 12:
1300 divided by 161 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 563621.6708
The remainder is 12 after subtracting 1288 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
If we divide 120 by 161, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 563621.6708
Subtracting 0 from 120 leaves us 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 14:
If we divide 1200 by 161, we get 7 and a remainder of 73.
The next digit of our result is 7. 
Result so far: 563621.670807
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.

On to step 15:
161 goes into 730 4 times with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 563621.6708074
Deduct 644 from 730 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 16:
When dividing 860 by 161, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 563621.67080745
The remainder is 55 after subtracting 805 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 563621.67080745, with a leftover of 5.5e-08.
