121433 ÷ 87 
We want to divide 121433 by 87.

Let's proceed to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 87

Moving on to step 2:
12 divided by 87 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 87

Going ahead to step 3:
The number 87 fits into 121 1 times, leaving a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 87 away from 121, we end up with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 87

Going ahead to step 4:
87 can be fit into 344 3 times, resulting in a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 261 from 344 to get 83.
Bring next digit (3) of the dividend behind the 83 and repeat the process: 833 / 87

Let's proceed to step 5:
87 goes into 833 9 times with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 139.0
The remainder is 50 after subtracting 783 from 833.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 87

Advancing to step 6:
If we divide 503 by 87, we get 5 and a remainder of 68.
The next digit of our result is 5. 
Result so far: 1395.0
If we subtract 435 from 503, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
87 goes into 680 7 times with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 1395.7
Subtracting 609 from 680 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 8:
If we divide 710 by 87, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 1395.78
If we subtract 696 from 710, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 87 is 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1395.781
If we take 87 away from 140, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 10:
The number 87 fits into 530 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1395.7816
The remainder is 8 after subtracting 522 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 87 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1395.7816
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
If we divide 800 by 87, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 1395.781609
Deduct 783 from 800 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
170 divided by 87 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 1395.7816091
Subtracting 87 from 170 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 14:
87 can be fit into 830 9 times, resulting in a remainder of 47.
The next digit of our result is 9. 
Result so far: 1395.78160919
Subtracting 783 from 830 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 1395.78160919, and the remainder is 4.7e-08.
