We're dividing 354186 by 89 
Our goal is to divide 354186 by 89.

Advancing to step 1:
When dividing 3 by 89, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 89

Moving on to step 2:
89 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 89

Going ahead to step 3:
The number 89 fits into 354 3 times, leaving a remainder of 87.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 267 from 354 and we're left with 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 89

Step 4:
If we divide 871 by 89, we get 9 and a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 801 from 871 leaves us with 70.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 89

Advancing to step 5:
If we divide 708 by 89, we get 7 and a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
If we take 623 away from 708, we end up with 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 89

Advancing to step 6:
The number 89 fits into 856 9 times, leaving a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 3979.0
The remainder is 55 after subtracting 801 from 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 7:
89 goes into 550 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3979.6
The remainder is 16 after subtracting 534 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
The number 89 fits into 160 1 times, leaving a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 3979.61
If we subtract 89 from 160, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
The number 89 fits into 710 7 times, leaving a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 3979.617
Deduct 623 from 710 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 10:
The number 89 fits into 870 9 times, leaving a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 3979.6179
The remainder is 69 after subtracting 801 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
89 can be fit into 690 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 3979.61797
If we subtract 623 from 690, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
89 can be fit into 670 7 times, resulting in a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 3979.617977
The remainder is 47 after subtracting 623 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 3979.617977, and the remainder is 4.7e-06.
