98974734 ÷ 621 
We're looking to find how many times 621 goes into 98974734.

Going ahead to step 1:
When dividing 9 by 621, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 621

Moving on to step 2:
The number 621 fits into 98 0 times, leaving a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Fetch the next digit (9) from the dividend, attach it to 98 and continue: 989 / 621

Let's proceed to step 3:
The number 621 fits into 989 1 times, leaving a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 621 away from 989, we end up with 368.
Fetch the next digit (7) from the dividend, attach it to 368 and continue: 3687 / 621

Step 4:
The number 621 fits into 3687 5 times, leaving a remainder of 582.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 3105 from 3687, we get 582.
Include the next digit (4) from the dividend after 582, then repeat: 5824 / 621

Going ahead to step 5:
The number 621 fits into 5824 9 times, leaving a remainder of 235.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we subtract 5589 from 5824, we get 235.
Include the next digit (7) from the dividend after 235, then repeat: 2357 / 621

On to step 6:
The number 621 fits into 2357 3 times, leaving a remainder of 494.
Write down 3 as next digit of the result. 
Result so far: 1593.0
Deduct 1863 from 2357 and we're left with 494.
Fetch the next digit (3) from the dividend, attach it to 494 and continue: 4943 / 621

Step 7:
621 can be fit into 4943 7 times, resulting in a remainder of 596.
Use 7 as the next digit of our solution. 
Result so far: 15937.0
Deduct 4347 from 4943 and we're left with 596.
Fetch the next digit (4) from the dividend, attach it to 596 and continue: 5964 / 621

Advancing to step 8:
When dividing 5964 by 621, we get 9 with a remainder of 375.
Put 9 as the next digit of the answer. 
Result so far: 159379.0
If we subtract 5589 from 5964, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 9:
If we divide 3750 by 621, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 159379.6
If we subtract 3726 from 3750, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 621, we get 0 and a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 159379.6
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
2400 divided by 621 is 3 with a remainder of 537.
Write down 3 as next digit of the result. 
Result so far: 159379.603
If we subtract 1863 from 2400, we get 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 12:
621 can be fit into 5370 8 times, resulting in a remainder of 402.
Record the quotient 8 as the next digit in the result. 
Result so far: 159379.6038
Deduct 4968 from 5370 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 13:
The number 621 fits into 4020 6 times, leaving a remainder of 294.
The next digit of our result is 6. 
Result so far: 159379.60386
The remainder is 294 after subtracting 3726 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 14:
When dividing 2940 by 621, we get 4 with a remainder of 456.
Record the quotient 4 as the next digit in the result. 
Result so far: 159379.603864
Subtract 2484 from 2940 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 15:
If we divide 4560 by 621, we get 7 and a remainder of 213.
The next digit of our result is 7. 
Result so far: 159379.6038647
Subtracting 4347 from 4560 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 16:
621 goes into 2130 3 times with a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 159379.60386473
Subtract 1863 from 2130 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

The final outcome is 159379.60386473, with a leftover of 2.67e-07.
