73970839 divided by 89 
We want to divide 73970839 by 89.

Moving on to step 1:
7 divided by 89 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 89

Going ahead to step 2:
If we divide 73 by 89, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 89

Step 3:
89 can be fit into 739 8 times, resulting in a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 712 away from 739, we end up with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 89

Let's proceed to step 4:
The number 89 fits into 277 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 267 away from 277, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 89

Going ahead to step 5:
The number 89 fits into 100 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 831.0
Subtract 89 from 100 to get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 89

Going ahead to step 6:
If we divide 118 by 89, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 8311.0
Subtracting 89 from 118 leaves us with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 89

Moving on to step 7:
When dividing 293 by 89, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 83113.0
If we take 267 away from 293, we end up with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 89

Going ahead to step 8:
If we divide 269 by 89, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 831133.0
Deduct 267 from 269 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
89 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 831133.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
89 can be fit into 200 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 831133.02
Deduct 178 from 200 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
89 goes into 220 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 831133.022
The remainder is 42 after subtracting 178 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 831133.022 and a remainder of 0.0042.
