We're dividing 57170920 by 209 
We're looking to find how many times 209 goes into 57170920.

On to step 1:
The number 209 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 209

Going ahead to step 2:
If we divide 57 by 209, we get 0 and a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 209

Step 3:
571 divided by 209 is 2 with a remainder of 153.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 418 from 571 and we're left with 153.
Take the next digit (7) from the dividend and append it to 153, then repeat: 1537 / 209

Step 4:
1537 divided by 209 is 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 1463 from 1537 and we're left with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 209

Moving on to step 5:
The number 209 fits into 740 3 times, leaving a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 273.0
If we take 627 away from 740, we end up with 113.
Take the next digit (9) from the dividend and append it to 113, then repeat: 1139 / 209

Going ahead to step 6:
When dividing 1139 by 209, we get 5 with a remainder of 94.
Record the quotient 5 as the next digit in the result. 
Result so far: 2735.0
Deduct 1045 from 1139 and we're left with 94.
Fetch the next digit (2) from the dividend, attach it to 94 and continue: 942 / 209

Moving on to step 7:
209 can be fit into 942 4 times, resulting in a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 27354.0
Subtracting 836 from 942 leaves us with 106.
Append the next digit (0) from the dividend to 106 and continue with: 1060 / 209

Moving on to step 8:
209 goes into 1060 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 273545.0
Subtract 1045 from 1060 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.

Going ahead to step 9:
If we divide 150 by 209, we get 0 and a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 273545.0
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
If we divide 1500 by 209, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 273545.07
Deduct 1463 from 1500 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
If we divide 370 by 209, we get 1 and a remainder of 161.
The next digit of our result is 1. 
Result so far: 273545.071
Deduct 209 from 370 and we're left with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 12:
1610 divided by 209 is 7 with a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 273545.0717
Subtracting 1463 from 1610 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 13:
209 goes into 1470 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 273545.07177
If we take 1463 away from 1470, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 273545.07177 and a remainder of 7e-06.
