Let's divide 78939846 by 213
We want to divide 78939846 by 213.

On to step 1:
The number 213 fits into 7 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 213

Let's proceed to step 2:
When dividing 78 by 213, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 213

Moving on to step 3:
789 divided by 213 is 3 with a remainder of 150.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 639 from 789, we get 150.
Take the next digit (3) from the dividend and append it to 150, then repeat: 1503 / 213

Moving on to step 4:
213 can be fit into 1503 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 1491 from 1503 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 213

Let's proceed to step 5:
When dividing 129 by 213, we get 0 with a remainder of 129.
Write down 0 as next digit of the result. 
Result so far: 370.0
Subtract 0 from 129 to get 129.
Take the next digit (8) from the dividend and append it to 129, then repeat: 1298 / 213

Going ahead to step 6:
213 can be fit into 1298 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3706.0
The remainder is 20 after subtracting 1278 from 1298.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 213

Moving on to step 7:
213 goes into 204 0 times with a remainder of 204.
Use 0 as the next digit of our solution. 
Result so far: 37060.0
If we subtract 0 from 204, we get 204.
Fetch the next digit (6) from the dividend, attach it to 204 and continue: 2046 / 213

On to step 8:
2046 divided by 213 is 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 370609.0
If we subtract 1917 from 2046, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 9:
213 goes into 1290 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 370609.6
If we take 1278 away from 1290, we end up 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.

Let's proceed to step 10:
The number 213 fits into 120 0 times, leaving a remainder of 120.
The next digit of our result is 0. 
Result so far: 370609.6
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
1200 divided by 213 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 370609.605
Subtracting 1065 from 1200 leaves us 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.

Step 12:
213 can be fit into 1350 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 370609.6056
Subtract 1278 from 1350 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.

Moving on to step 13:
The number 213 fits into 720 3 times, leaving a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 370609.60563
If we take 639 away from 720, we end up 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 14:
When dividing 810 by 213, we get 3 with a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 370609.605633
Deduct 639 from 810 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Our division results in 370609.605633 with a remaining 1.71e-05.
