We divide 79089681 by 213
We want to divide 79089681 by 213.

Going ahead to step 1:
213 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 213

Moving on to step 2:
When dividing 79 by 213, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 213

Moving on to step 3:
When dividing 790 by 213, we get 3 with a remainder of 151.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 639 from 790, we get 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 213

On to step 4:
When dividing 1518 by 213, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 27 after subtracting 1491 from 1518.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 213

Advancing to step 5:
The number 213 fits into 279 1 times, leaving a remainder of 66.
The next digit of our result is 1. 
Result so far: 371.0
Subtract 213 from 279 to get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 213

Going ahead to step 6:
213 goes into 666 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 3713.0
Subtracting 639 from 666 leaves us with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 213

Moving on to step 7:
213 can be fit into 278 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 37131.0
Subtract 213 from 278 to get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 213

Let's proceed to step 8:
The number 213 fits into 651 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 371313.0
Deduct 639 from 651 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 213, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 371313.0
The remainder is 120 after subtracting 0 from 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 10:
If we divide 1200 by 213, we get 5 and a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 371313.05
Deduct 1065 from 1200 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 11:
If we divide 1350 by 213, we get 6 and a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 371313.056
Deduct 1278 from 1350 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
When dividing 720 by 213, we get 3 with a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 371313.0563
Subtracting 639 from 720 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
If we divide 810 by 213, we get 3 and a remainder of 171.
Write down 3 as next digit of the result. 
Result so far: 371313.05633
Subtract 639 from 810 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The final result is 371313.05633 with a remainder of 0.000171.
