We look at the division of 3971285 by 169 
We want to divide 3971285 by 169.

Step 1:
The number 169 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 169

Moving on to step 2:
39 divided by 169 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 169

Let's proceed to step 3:
397 divided by 169 is 2 with a remainder of 59.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 59 after subtracting 338 from 397.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 169

Step 4:
169 goes into 591 3 times with a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 84 after subtracting 507 from 591.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 169

Step 5:
If we divide 842 by 169, we get 4 and a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 676 from 842 leaves us with 166.
Include the next digit (8) from the dividend after 166, then repeat: 1668 / 169

Step 6:
The number 169 fits into 1668 9 times, leaving a remainder of 147.
Record the quotient 9 as the next digit in the result. 
Result so far: 2349.0
Deduct 1521 from 1668 and we're left with 147.
Bring next digit (5) of the dividend behind the 147 and repeat the process: 1475 / 169

Let's proceed to step 7:
169 goes into 1475 8 times with a remainder of 123.
Use 8 as the next digit of our solution. 
Result so far: 23498.0
If we subtract 1352 from 1475, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 8:
169 can be fit into 1230 7 times, resulting in a remainder of 47.
The next digit of our result is 7. 
Result so far: 23498.7
Subtract 1183 from 1230 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
169 goes into 470 2 times with a remainder of 132.
Use 2 as the next digit of our solution. 
Result so far: 23498.72
The remainder is 132 after subtracting 338 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
169 goes into 1320 7 times with a remainder of 137.
The next digit of our result is 7. 
Result so far: 23498.727
If we subtract 1183 from 1320, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 11:
1370 divided by 169 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 23498.7278
If we subtract 1352 from 1370, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
When dividing 180 by 169, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 23498.72781
Subtracting 169 from 180 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
169 goes into 110 0 times with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 23498.72781
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 14:
When dividing 1100 by 169, we get 6 with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 23498.7278106
If we subtract 1014 from 1100, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 15:
860 divided by 169 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 23498.72781065
Subtracting 845 from 860 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 23498.72781065, and the remainder is 1.5e-08.
