We're dividing 89351421 by 612 
We want to divide 89351421 by 612.

On to step 1:
612 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 612

Step 2:
612 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Include the next digit (3) from the dividend after 89, then repeat: 893 / 612

Step 3:
If we divide 893 by 612, we get 1 and a remainder of 281.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 612 from 893 to get 281.
Fetch the next digit (5) from the dividend, attach it to 281 and continue: 2815 / 612

Let's proceed to step 4:
2815 divided by 612 is 4 with a remainder of 367.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 2448 from 2815 leaves us with 367.
Fetch the next digit (1) from the dividend, attach it to 367 and continue: 3671 / 612

On to step 5:
The number 612 fits into 3671 5 times, leaving a remainder of 611.
Write down 5 as next digit of the result. 
Result so far: 145.0
The remainder is 611 after subtracting 3060 from 3671.
Include the next digit (4) from the dividend after 611, then repeat: 6114 / 612

Advancing to step 6:
612 goes into 6114 9 times with a remainder of 606.
The number 9 becomes the next digit in our result. 
Result so far: 1459.0
The remainder is 606 after subtracting 5508 from 6114.
Include the next digit (2) from the dividend after 606, then repeat: 6062 / 612

Going ahead to step 7:
612 can be fit into 6062 9 times, resulting in a remainder of 554.
Use 9 as the next digit of our solution. 
Result so far: 14599.0
If we subtract 5508 from 6062, we get 554.
Fetch the next digit (1) from the dividend, attach it to 554 and continue: 5541 / 612

Advancing to step 8:
The number 612 fits into 5541 9 times, leaving a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 145999.0
Subtracting 5508 from 5541 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 612 fits into 330 0 times, leaving a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 145999.0
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
3300 divided by 612 is 5 with a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 145999.05
Subtract 3060 from 3300 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
612 can be fit into 2400 3 times, resulting in a remainder of 564.
Put 3 as the next digit of the answer. 
Result so far: 145999.053
Deduct 1836 from 2400 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 12:
The number 612 fits into 5640 9 times, leaving a remainder of 132.
Put 9 as the next digit of the answer. 
Result so far: 145999.0539
Deduct 5508 from 5640 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
When dividing 1320 by 612, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 145999.05392
If we take 1224 away from 1320, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
612 can be fit into 960 1 times, resulting in a remainder of 348.
Record the quotient 1 as the next digit in the result. 
Result so far: 145999.053921
The remainder is 348 after subtracting 612 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 15:
If we divide 3480 by 612, we get 5 and a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 145999.0539215
Subtracting 3060 from 3480 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 16:
612 goes into 4200 6 times with a remainder of 528.
The number 6 becomes the next digit in our result. 
Result so far: 145999.05392156
Subtracting 3672 from 4200 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final result is 145999.05392156 with a remainder of 5.28e-07.
