84090974 ÷ 428 
We want to divide 84090974 by 428.

Advancing to step 1:
428 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 428

On to step 2:
428 can be fit into 84 0 times, resulting in a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 428

Advancing to step 3:
840 divided by 428 is 1 with a remainder of 412.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 428 from 840 and we're left with 412.
Take the next digit (9) from the dividend and append it to 412, then repeat: 4129 / 428

On to step 4:
428 goes into 4129 9 times with a remainder of 277.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 3852 from 4129 leaves us with 277.
Grab the next digit (0) from the dividend, add it to 277, then carry on: 2770 / 428

Let's proceed to step 5:
428 goes into 2770 6 times with a remainder of 202.
The next digit of our result is 6. 
Result so far: 196.0
If we subtract 2568 from 2770, we get 202.
Fetch the next digit (9) from the dividend, attach it to 202 and continue: 2029 / 428

Going ahead to step 6:
When dividing 2029 by 428, we get 4 with a remainder of 317.
Write down 4 as next digit of the result. 
Result so far: 1964.0
Subtracting 1712 from 2029 leaves us with 317.
Take the next digit (7) from the dividend and append it to 317, then repeat: 3177 / 428

Going ahead to step 7:
3177 divided by 428 is 7 with a remainder of 181.
The next digit of our result is 7. 
Result so far: 19647.0
If we take 2996 away from 3177, we end up with 181.
Fetch the next digit (4) from the dividend, attach it to 181 and continue: 1814 / 428

Let's proceed to step 8:
The number 428 fits into 1814 4 times, leaving a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 196474.0
Subtract 1712 from 1814 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
If we divide 1020 by 428, we get 2 and a remainder of 164.
The next digit of our result is 2. 
Result so far: 196474.2
Subtract 856 from 1020 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 10:
428 can be fit into 1640 3 times, resulting in a remainder of 356.
Use 3 as the next digit of our solution. 
Result so far: 196474.23
The remainder is 356 after subtracting 1284 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 11:
The number 428 fits into 3560 8 times, leaving a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 196474.238
If we take 3424 away from 3560, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 12:
428 can be fit into 1360 3 times, resulting in a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 196474.2383
If we subtract 1284 from 1360, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
When dividing 760 by 428, we get 1 with a remainder of 332.
Use 1 as the next digit of our solution. 
Result so far: 196474.23831
Deduct 428 from 760 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 14:
428 goes into 3320 7 times with a remainder of 324.
The next digit of our result is 7. 
Result so far: 196474.238317
If we subtract 2996 from 3320, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 15:
428 can be fit into 3240 7 times, resulting in a remainder of 244.
Put 7 as the next digit of the answer. 
Result so far: 196474.2383177
Subtract 2996 from 3240 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The quotient of the division is 196474.2383177, and the remainder is 2.44e-06.
