We're dividing 21998107 by 155 
Let's see how many times 155 fits into 21998107.

Step 1:
If we divide 2 by 155, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 155

Moving on to step 2:
21 divided by 155 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 155

Moving on to step 3:
When dividing 219 by 155, we get 1 with a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 155 from 219 leaves us with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 155

On to step 4:
649 divided by 155 is 4 with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 620 from 649 leaves us with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 155

Step 5:
The number 155 fits into 298 1 times, leaving a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 141.0
If we take 155 away from 298, we end up with 143.
Append the next digit (1) from the dividend to 143 and continue with: 1431 / 155

Let's proceed to step 6:
When dividing 1431 by 155, we get 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 1419.0
Subtracting 1395 from 1431 leaves us with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 155

Let's proceed to step 7:
If we divide 360 by 155, we get 2 and a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 14192.0
The remainder is 50 after subtracting 310 from 360.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 155

Step 8:
The number 155 fits into 507 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 141923.0
If we subtract 465 from 507, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
The number 155 fits into 420 2 times, leaving a remainder of 110.
Record the quotient 2 as the next digit in the result. 
Result so far: 141923.2
The remainder is 110 after subtracting 310 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
The number 155 fits into 1100 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 141923.27
Subtract 1085 from 1100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
155 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 141923.27
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
The number 155 fits into 1500 9 times, leaving a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 141923.2709
The remainder is 105 after subtracting 1395 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 13:
1050 divided by 155 is 6 with a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 141923.27096
Deduct 930 from 1050 and we're left 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.

On to step 14:
155 goes into 1200 7 times with a remainder of 115.
The number 7 becomes the next digit in our result. 
Result so far: 141923.270967
If we take 1085 away from 1200, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 15:
155 can be fit into 1150 7 times, resulting in a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 141923.2709677
Subtracting 1085 from 1150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 141923.2709677, and the remainder is 6.5e-07.
