We divide 645920 by 98
We're looking to find how many times 98 goes into 645920.

Advancing to step 1:
6 divided by 98 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 98

Step 2:
98 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 98

Advancing to step 3:
645 divided by 98 is 6 with a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 588 away from 645, we end up with 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 98

Going ahead to step 4:
98 can be fit into 579 5 times, resulting in a remainder of 89.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Deduct 490 from 579 and we're left with 89.
Fetch the next digit (2) from the dividend, attach it to 89 and continue: 892 / 98

On to step 5:
When dividing 892 by 98, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
Deduct 882 from 892 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 98

Let's proceed to step 6:
The number 98 fits into 100 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 6591.0
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 98, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6591.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
98 goes into 200 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 6591.02
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 98, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6591.02
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
98 can be fit into 400 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 6591.0204
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
98 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6591.0204
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
98 can be fit into 800 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6591.020408
If we subtract 784 from 800, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 98 fits into 160 1 times, leaving a remainder of 62.
The next digit of our result is 1. 
Result so far: 6591.0204081
If we take 98 away from 160, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
If we divide 620 by 98, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 6591.02040816
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 6591.02040816, with a leftover of 3.2e-08.
