We're dividing 19478399 by 161 
We're looking to find how many times 161 goes into 19478399.

On to step 1:
161 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 161

Let's proceed to step 2:
The number 161 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 161

Advancing to step 3:
161 goes into 194 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 161 from 194 and we're left with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 161

Going ahead to step 4:
161 goes into 337 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 322 from 337 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 161

Let's proceed to step 5:
158 divided by 161 is 0 with a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 120.0
Deduct 0 from 158 and we're left with 158.
Include the next digit (3) from the dividend after 158, then repeat: 1583 / 161

On to step 6:
161 goes into 1583 9 times with a remainder of 134.
Use 9 as the next digit of our solution. 
Result so far: 1209.0
The remainder is 134 after subtracting 1449 from 1583.
Include the next digit (9) from the dividend after 134, then repeat: 1349 / 161

Going ahead to step 7:
1349 divided by 161 is 8 with a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 12098.0
Deduct 1288 from 1349 and we're left with 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 161

Going ahead to step 8:
161 goes into 619 3 times with a remainder of 136.
The next digit of our result is 3. 
Result so far: 120983.0
The remainder is 136 after subtracting 483 from 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 9:
If we divide 1360 by 161, we get 8 and a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 120983.8
Subtract 1288 from 1360 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
The number 161 fits into 720 4 times, leaving a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 120983.84
The remainder is 76 after subtracting 644 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
161 goes into 760 4 times with a remainder of 116.
The next digit of our result is 4. 
Result so far: 120983.844
If we take 644 away from 760, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 120983.844, and the remainder is 0.0116.
